Brussels · Interim counsel
Day-rate and monthly-retainer counsel for a general counsel, a chief compliance officer, or a chief operating officer whose Brussels filing will not wait for an 11-week permanent search.
Interim legal talent Brussels is day-rate or monthly-retainer counsel for a gap a permanent hire will not cover in time. Sartori & Partners closed 28 Brussels interim searches over three years, at a 93 percent completion rate, on a typical timeline of 2 to 5 weeks from signed brief to start. A Belgian bank in Brussels put interim DORA counsel on an ICT-register file in 3 weeks in 2026. The French-language Brussels Bar listed 3,657 lawyers on the roll on 1 July 2026. Belgium set the 2025-2026 wage-cost margin at 0 percent.
01 — The brief answer
Interim legal talent Brussels is the brief a general counsel, a chief compliance officer, or a chief operating officer opens when the work has a date and the permanent seat does not. The date is a DORA register, a competition response, an AI Act transparency file, or a leave. The permanent seat, if the company still wants one, is a different clock: 52 general counsel and chief legal officer placements inside 400+ placements since 2017 (230+ in-house), a shortlist in 24 days, and a median accepted offer in 11 weeks.
Sartori & Partners was founded in early 2017 by Lorenzo Sartori. The Brussels network opened in 2019. Across 60+ interim and fractional engagements since 2017, the firm-wide median from first call to start is 7 days. That book sits outside the 400+ placements (230+ in-house). The Brussels interim line is a city cut of the same book, and it is slower. We have worked the Brussels market for 8 years. Over the last three years we closed 28 Brussels interim searches at a 93 percent completion rate, on a typical timeline of 2 to 5 weeks from signed brief to start. The practice page is interim and contract counsel. The city hub is legal recruitment in Brussels.

Brussels interim line, trailing three years. Written offer to acceptance on those 28 ran 7 working days. A counter-offer arrived on 20 percent. The city’s one interview cohort is 250. Firm-wide interim engagements are 60+, median 7 days from first call to start. Those 7 days are not the 7 working days above, and they are not a second Brussels count.
02 — Local demand
Regulation (EU) 2022/2554, the Digital Operational Resilience Act, applies from 17 January 2025. The FSMA’s notice of 17 February 2026 records what that date produced in Belgium: in 2025, companies subject to DORA filed a register of agreements with third-party ICT providers, and in 2026 only a limited set of companies must file again. An unchanged register can be confirmed. A changed register is updated or replaced. A general counsel at a Brussels financial firm who still has an ICT contract without the register fields is not waiting on a strategy paper. The supervisor has already run the exercise once.
The cybersecurity calendar sits next to it, and it is not the same statute. The Centre for Cybersecurity Belgium states that the Law of 26 April 2024, transposing Directive (EU) 2022/2555, entered into force on 18 October 2024. Entities at assurance level Essential had until 18 April 2026 to obtain a Basic or Important verification, and they have until 18 April 2027 to obtain Essential certification from an accredited conformity assessment body. The 18 April 2026 verification date has passed. The live date for an Essential entity is 18 April 2027. DORA is the sector rule for financial entities. The NIS2 law is the horizontal rule for the entities the Centre has in scope. A brief that treats them as one “cyber” hire is two files.
Competition demand is a published list, not a mood. The Belgian Competition Authority’s priorities paper for 2026, published on 27 February 2026, names five sectors: agri-food, digitalisation and telecommunications, healthcare, basic services, and sport, media and entertainment. The same paper records a public consultation, in press release 42/2025 of 15 October 2025, on fiber commitments offered by Proximus/Fiberklaar and Telenet/Wyre, and an ex officio investigation, in press release 33/2025 of 31 July 2025, into the draft cooperation between Proximus and Orange Belgium on fiber in Wallonia. A project counsel seat on one of those files is a dated response. It is not a standing competition department.
The AI Act calendar moved in 2026, and the move matters for what a Brussels company should staff now. The European Commission states that the Act entered into force on 1 August 2024 and applies from 2 August 2026, with exceptions: prohibited practices and AI literacy from 2 February 2025, and governance plus general-purpose model obligations from 2 August 2025. Regulation (EU) 2026/1744, in force on 27 July 2026, moved Annex III high-risk rules to 2 December 2027 and Annex I high-risk rules to 2 August 2028. A general counsel who briefed “high-risk compliance by August 2026” briefed a date the amendment removed. The work that did land on 2 August 2026 is transparency, literacy, and the start of enforcement. The high-risk build is a 2027 and 2028 file.
The bars that can take the independent version of that work are counted, and they are two orders, not one. The French-language Brussels Bar, on its own figures page, lists 3,657 lawyers on the roll as of 1 July 2026, plus 937 trainees, 531 members of other EU bars, and 136 lawyers from bars outside the EU. The Dutch-language order, on its own page, counted 4,133 lawyers on 26 March 2026: 2,755 on the tableau, of whom 2,661 have a principal office and 94 a branch, plus 838 trainees, 244 on the EU list, 141 on the B list, and 155 honorary lawyers. Those two totals are not added here. The roll and the tableau are different cuts from the trainees, the EU lists, and the honorary list. The Institute of Company Lawyers, established by the Law of 1 March 2000, states that it has more than 2,300 members. That is the employed bar. It is not a slice of either roll.
03 — Sector mix
The 28 closed Brussels interim searches split once, and only once. 10 were competition, merger, or foreign-subsidy project seats. 7 were financial-sector seats on DORA and ICT registers. 6 were NIS2 or AI Act product-regulatory seats. 5 were leave or vacancy cover on a counsel or general-counsel chair. Ten, seven, six, and five are 28. A second cut of the same book is not a fifth sector: 3 of the 28 closed only after the first day-rate was rewritten, because the brief had not chosen between an independent advocaat and a company lawyer on payroll.
The competition slice follows the Authority’s five sectors and the fiber files already in its paper, not a generic “EU regulatory” label. A response to a cooperation consultation is a defined set of clauses, a counterparty, and a date. It is the work a counsel who has already marked a concentration filing can take without a quarter of onboarding. It is also the work that stalls when the company asks for the Institute title and the only available lawyer will work as an independent counsel. That mismatch is the whole of the 3. The bank file below is one of them, and one of the 7: the first shortlist mixed the two titles, and the rate was rewritten once the company chose independent counsel.
The financial slice follows the FSMA’s 17 February 2026 notice, not a generic “banking” label. The NIS2 and AI Act slice follows two calendars that a single “digital counsel” title collapses: 18 April 2027 for Essential certification, and 2 August 2026 for the rules that actually applied, with high-risk Annex III deferred to 2 December 2027. The leave slice is the chair that cannot be empty while notice runs or while an Institute file is prepared: parental leave, a medical leave, or the weeks between a resignation and a retained search. Mapping coverage for the city is 6,000 lawyers, inside a firm market map of 1,480,000+ lawyers. That map is a coverage figure. It is not a count of people clear of conflicts on Monday.
A counter-offer arrived on 20 percent of the 28. On a day-rate, the counter-offer is often a permanent conversion, or a base increase that keeps the lawyer in the current job through the filing. It is not a partner-line contest over a guarantee. The 93 percent completion rate is the share of Brussels interim mandates in this window that reached a start. It is not a claim that every brief was the right brief. The 3 rewritten rates are the part of the book that should have been scoped before the first number went to the lawyer.
04 — Compensation
Interim counsel is a day-rate or a monthly retainer. It is not a percentage of salary. If the company later converts the seat to a retained search, the days already billed are credited against that fee. The retained fee is 25–30 percent of the hire’s total first-year compensation. Thirty percent of the fee is paid as a retainer at engagement and is kept if the client cancels. The replacement term on a retained general counsel, chief legal officer, or chief compliance officer search is 12 months. Those are the firm terms. They are not a Brussels tariff. Published United States interim general counsel day-rates are $1,800–$3,200. They are not a euro rate for this city. A Brussels euro day-rate is not in the firm record.
A day-rate that ignores the cash the lawyer already has will not close, and in 2026 that cash is boxed by a statute. The FPS Employment page on the wage norm records that the royal decree of 12 September 2025, published in the Belgian Official Gazette on 22 September 2025, sets the maximum margin for wage-cost growth in 2025-2026 at 0 percent, under the Act of 26 July 1996. Indexation and scale increases remain guaranteed and are not counted inside the margin. A breach can draw a fine of €250 to €5,000, multiplied by the employees concerned, with a cap of 100 employees. An employed conversion is a wage-norm problem. A day-rate paid to an independent counsel is not that wage. Mixing the two in one number is how a brief gets the title wrong.
The dated cash for the employed seat and the officer seat sits on the salary pages, and it is not an interim rate. Read in-house counsel salary in Brussels, 2026 for the employed seat and general counsel salary in Brussels, 2026 for the officer seat. The permanent Brussels desk, if the cover should become a hire, is in-house legal recruiters in Brussels. A company that averages those pages into one “Brussels lawyer” number and then backs into a day-rate is pricing a different job than the one it will brief.
The title changes the cash as well as the name. The Institute’s fee page, adopted by the Council on 15 December 2020 and amended on 7 December 2023, sets the member fee at €414 a year, €394 if the company or group has at least 30 members, and €207 in the first year if the Council approves membership after 31 August. The joining page requires the employment contract in the file. The English page lists a Council meeting on 14 December 2026 for a complete file received before 26 November 2026. A day-rate engagement that is truly independent does not create that membership. A conversion onto payroll does. The weeks that file takes are why a Brussels start can sit outside the firm-wide 7-day median even when the person is already known. The 7 working days from written offer to acceptance measure the decision after the rate and the title are written down. They are not the firm-wide median of 7 days from first call to start. They do not measure the Council.
The FSMA register could not wait for an 11-week general counsel search. Counsel was on the ICT file in 3 weeks, and the days billed sit as a credit if we convert the seat.
That sentence is from the general counsel of a Belgian bank in Brussels, on the file below. The 11 weeks are the firm median to an accepted offer on 52 general counsel and chief legal officer searches. The 3 weeks are this file’s start, inside the Brussels interim timeline of 2 to 5 weeks.
05 — Timeline
The firm-wide interim clock is 7 days. That is the median from first call to start across 60+ interim and fractional engagements since 2017. A published file beat it: a Series C fintech in San Francisco had an interim general counsel live on day 6, for parental leave and a financing. That file is not a Brussels file. It is the evidence that a pre-cleared bench can start inside a week when the title question is an American contractor question.
The Brussels interim clock is 2 to 5 weeks from signed brief to start, on 28 closed searches over three years. The same files ran 7 working days from written offer to acceptance. A counter-offer arrived on 20 percent. Those 7 working days are the decision after the rate and the title are written down. They are not the firm-wide median of 7 days from first call to start. The two clocks share a numeral. They do not share a start point, a base, or a unit. The wider Brussels timeline is the choice between an independent advocaat and a company lawyer on payroll, the language of the contract set, and notice if the person is already employed.
Notice is the reason a conversion is not a start date. For a contract whose execution started on or after 1 January 2014 and before 1 June 2026, the FPS Employment table gives the employer 18 weeks at five years of service to under six, and 33 weeks at ten years to under eleven. Contracts starting on or after 1 June 2026 and before 1 August 2026 use that table with a cap of 52 weeks from 17 years of seniority. Contracts starting on or after 1 August 2026 carry one week in the first six months and the same 52-week cap from 17 years. An interim who stays independent is not on that table. An interim who is hired onto the payroll is. The table is why “start on Monday” and “employed by Friday” are different instructions.
If the seat should become permanent, a third clock starts. A general counsel or chief legal officer search reaches a shortlist in 24 days and an accepted offer in a median of 11 weeks, range 8 to 16, across 38 such placements since 2017. The published Brussels specialist file on that permanent book is privacy and AI-governance counsel for a Euronext-listed insurer: a bilingual shortlist, 19 days to shortlist, an accepted offer in 8 weeks. Days billed on the interim engagement credit against the retained fee. The Brussels interim timeline does not shrink the 11 weeks, and it is not that 8-week specialist file. It covers the gap while those weeks run, or it covers a project that ends and never becomes a search. The comparison between the two products is on interim versus permanent in-house counsel.
06 — Two files
Both files are inside the 28. The bank file is one of the 7. The telecoms file is one of the 10. Neither names a company.
07 — How the work is run
A Brussels interim engagement opens on a written brief: the matter list, the seniority, the language of the contract set, the day-rate or retainer authority, the choice between an independent advocaat and a company lawyer on payroll, the conflicts that are not negotiable, and a start inside 2 to 5 weeks. The interview cohort for the city is 250 structured interviews. The mandate figures are closed files, not a slice of that cohort.
Outreach is confidential and sequential. Interest, recent matter ownership, rate, notice, and whether the lawyer can work without a new Institute admission are confirmed before a name reaches the company. Conflicts run before the first client interview when the book is an operator panel or a bank’s ICT vendors. 3 of the 28 still needed the rate rewritten. That is the failure mode this order is meant to catch earlier: a number that goes out before the title is chosen.
If the company converts the seat, the search becomes retained. The order of that search is the six labels below. They are the order of a permanent mandate, including resignation and the first hundred days. They are not six measured averages on the interim book. The interim measurement stops when counsel is on the work. The typical timeline is 2 to 5 weeks from signed brief to start on the closed Brussels interim mandates. The method is the one on our methodology. The research programme that holds the cohort is the research programme.

A general counsel, chief compliance officer, or chief operating officer hires it when a filing, a leave, or a contract set cannot wait for a permanent search. Interim legal talent Brussels is day-rate or monthly-retainer counsel, counted outside permanent placements. Sartori & Partners closed 28 Brussels interim searches over three years, at a 93 percent completion rate, on a typical timeline of 2 to 5 weeks from signed brief to start. The firm-wide median, across 60+ interim and fractional engagements since 2017, is 7 days from first call to start. The Brussels line is the slower city cut. The practice is interim and contract counsel. The city hub is legal recruitment in Brussels.
Of the 28 closed Brussels interim searches, 10 were competition, merger, or foreign-subsidy project seats, 7 were financial-sector seats on DORA and ICT registers, 6 were NIS2 or AI Act product-regulatory seats, and 5 were leave or vacancy cover. Those four counts are the whole book. The Belgian Competition Authority published its 2026 priorities paper on 27 February 2026, naming agri-food, digitalisation and telecommunications, healthcare, basic services, and sport, media and entertainment. The FSMA's notice of 17 February 2026 says the 2026 DORA register update is limited to firms the authority selects. The Centre for Cybersecurity Belgium sets 18 April 2027 as the further certification date for entities at assurance level Essential.
Only when the person is employed and will use the protected title juriste d'entreprise or bedrijfsjurist. The Institute, created by the Law of 1 March 2000, states that it has more than 2,300 members, and its joining page requires an employment contract or a statute with a Belgian employer. The annual fee is €414, or €207 in the first year if the Council approves membership after 31 August. An independent advocaat who stays on a bar roll does not open that file. Article 437 of the Judicial Code treats salaried work as incompatible with the profession of lawyer unless independence and the dignity of the bar are not compromised. A company that then hires the same person onto the payroll does open the Institute file.
On the 28 closed Brussels interim searches, the typical timeline from signed brief to start is 2 to 5 weeks. From written offer to acceptance, the same files ran 7 working days. A counter-offer arrived on 20 percent of them. A Belgian bank in Brussels put interim DORA counsel on an ICT-register file in 3 weeks in 2026. A listed telecoms operator put project counsel on a fiber-cooperation response in 16 days. Both sit inside the 2 to 5 weeks timeline. They are not the firm-wide 7-day median from first call to start, which is measured across 60+ engagements since 2017. The 7 working days are offer to acceptance. They share only a numeral with that start median. For a contract that started on or after 1 January 2014 and before 1 June 2026, employer notice is 18 weeks at five years of service and 33 weeks at ten.
Interim work is a day-rate or a monthly retainer. Days billed are credited against a later retained fee if the company converts the seat. The retained fee, if that conversion is a search, is 25–30 percent of total first-year compensation. Thirty percent of that fee is the retainer at engagement, and it is kept if the client cancels. A Brussels euro day-rate is not in the firm record. The cash the lawyer can stay on is on in-house counsel salary in Brussels, 2026 and general counsel salary in Brussels, 2026. Belgium set the 2025-2026 wage-cost margin at 0 percent by royal decree of 12 September 2025. Indexation and scale increases stay outside that margin. 3 of the 28 Brussels interim files closed only after the first day-rate was rewritten.
When the gap is no longer a project with an end date. A permanent general counsel or chief legal officer search is a different book: 52 of 400+ placements since 2017 (230+ in-house), a shortlist in 24 days, and a median accepted offer in 11 weeks, range 8 to 16. The replacement term on that retained search is 12 months. Days already billed on the interim engagement credit against the retained fee. The Brussels interim clock, 2 to 5 weeks to start on 28 files, stops when the person is live. It does not replace the 11-week permanent clock. The published Brussels specialist file is permanent, not interim: privacy and AI-governance counsel for a Euronext-listed insurer, shortlist in 19 days, accepted offer in 8 weeks.
