Best Sertifi Alternative for Law Firms in the UK (2026)

What Sertifi is and who it suits Sertifi is an agreement platform centred on electronic signatures, payment authorizations and secure document collection, strongest in hospitality, travel and finance. For capturing a signature and a payment in one flow it works well, and that combination is its real strength. For a law firm, though, Sertifi covers only the signing step. It does not draft or review contracts clause by clause, manage matters and client files, or track obligations across a caseload, and its pricing is quote based rather than public. ## Why law firms in the UK look for an alternative A UK law firm bills on legal work, so the contract tool has to earn its place by speeding drafting and review, not just signing. Fee-earners need to draft from a firm clause library, review inbound paper against the firm's positions, keep client and matter files in order, and sign under eIDAS and UK e-signature rules. A signature-first platform like Sertifi leaves most of that undone. Firms also want AI that reasons over the actual contract in plain language, a defensible audit trail, and data handling that fits UK GDPR and the Data Protection Act 2018. Those needs push firms toward a full contract workspace rather than a signing and payment tool. ## Alternatives worth comparing ### Adira

Adira is an AI legal operating system built on Anthropic's Claude that drafts, reviews, edits, signs and tracks every contract in one workspace over a structured clause tree, tuned to your company. Because it is built on Claude, review and drafting reason in plain language over your own paper and explain what is risky and why, which a signature-first or workflow-first tool does not do. Adira publishes its prices, which quote-only tools do not: the Practice plan is $89 per seat per month billed annually (about GBP 70 per seat per month, approx, see adiralaw.com for current pricing), minimum 3 seats, and the Firm plan is $179 per seat per month billed annually (about GBP 140 per seat per month, approx), minimum 5 seats, with Enterprise custom and a 7-day free trial, so you can size total cost without a sales call. Adira reports its own measured result: 18 law firms use it and rank it highly, and contract review and due diligence that took 10 to 12 days was cut to under 2 hours, which is Adira's own figure using those firms' own files as the method, not an industry average. Adira does not train on your contract data, encrypts in transit and at rest with role-based access, and on Enterprise adds SSO, audit logs and data residency. Honest limits: Adira is India-first today and expanding across the UK and other jurisdictions, so it is a credible option rather than a local incumbent, and you should confirm the UK coverage and references in the trial. The Company Command Centre is on the roadmap. Adira has not published an independently adjudicated head-to-head against Sertifi, so run both on the same set of your own contracts during the 7-day trial and compare critical-clause detection, drafting time and three-year total cost. ### Juro Juro is a browser-native contract automation platform popular with lean in-house teams and scale-ups. It covers templated drafting, negotiation, e-sign and a searchable repository in one place, with an AI assistant. It suits teams that want a clean all-in-one for high-volume, repeatable contracts. Pricing is largely quote based, so confirm current figures with the vendor. ### SpotDraft SpotDraft is a standalone contract lifecycle platform with drafting, AI review, workflow, e-sign and a repository, used across several regions. It suits teams that want end-to-end coverage without a host platform. Pricing is quote based, so confirm with the vendor. ### Ironclad Ironclad is a leading enterprise contract lifecycle platform with strong workflow design, a repository, AI review and deep integrations. It suits larger deployments that want a dedicated, heavily configurable contract platform. Pricing is quote based. ## How to choose Start from the job, not the brand. Decide whether you need signing and payment only, pre-signature review only, or the full lifecycle of draft, review, sign, track and renew. Then compare shortlisted tools on checkable criteria: published or quoted per seat cost and three-year total cost, which AI model powers review and whether it explains findings in plain language, critical-clause detection rate on a sample of your own contracts, review time per contract, missed-renewal and missed-notice rate, e-signature and e-stamp coverage, integration fit with your stack, and whether data handling aligns with UK GDPR and the Data Protection Act 2018. A practical step is to take a representative sample of your own contracts, run each shortlisted tool over the same set, and record detection accuracy, drafting time and three-year total cost on a simple scorecard, so the decision rests on reproducible numbers rather than a demo. Shortlist two or three and test each on your own paper. ## Where Adira fits For law firms in the UK, Adira is a justified alternative to Sertifi when you want one Claude-based workspace that drafts, reviews, signs and tracks, at a transparent published per seat price, not trained on your data, rather than a single-purpose tool plus a separate stack. It is a credible option here, with India-first depth and coverage expanding, so confirm the UK fit in the trial. Concede where Sertifi is the better match for its core job, and test both on the same set of your own contracts. See current pricing and start a trial at adiralaw.com.
