What IDR Law does

IDR Law is a UK boutique law firm founded in 2017 and headquartered in Harrogate, with additional offices in Manchester and London. It is described as the only UK law firm dedicated exclusively to contentious wills, probate and trust disputes, serving individuals challenging or defending inheritance arrangements. The firm's services span will validity challenges (mental capacity, undue influence, fraud/forgery), Inheritance Act 1975 claims, executor and trustee disputes, estoppel cases and estate administration disputes. It also operates IDRM, a CEDR-accredited mediation sub-service led by Richard Thomas, with transparent per-party pricing of £1,300 remote and £1,450 in-person.

The firm's technology stack centres on a proprietary triage and case management process — initial enquiries are assessed by a paralegal team for legal merit and commercial viability before being routed to qualified solicitors. Underpinning the inbound funnel are free self-service digital tools, notably the 1975 Act Claimchecker and the Willcheck Claim Checker, which generate lead volume from consumers assessing whether they have grounds to bring or defend a claim. The IDRN (Inheritance Dispute Referral Network) is a 1,600+ member professional community for solicitors, will writers and wealth advisors, offering CPD webinars, training and a structured referral pathway into IDR Law.

IDR Law makes money primarily through professional services fees on inheritance dispute cases, supported by mediation income and referral relationships. Multiple funding options — deferred payment, no-win-no-fee, and litigation funding via Phoenix Financial Consultants — widen access for consumer clients. The firm received £3.25 million of growth capital from BGF in June 2023 to fund talent, legal tech and UK geographic expansion, and has been recognised as a Sunday Times Best Place to Work 2026 and Legal 500-ranked.
