Privilege & professional secrecy
Attorney-client privilege and EU professional-secrecy duties can be broken by one leaky integration. We enforce them with tenant boundaries, customer-managed keys and access logging aligned to ABA Model Rule 1.6.
Industries GDPR AI-native
LegalTech Software Development Services for US & EU Law Firms and In-House Counsel
YuSMP Group builds LegalTech for US and EU law firms, in-house legal departments and ALSPs. We engineer document automation and contract assembly, e-signature stacks aligned with eIDAS and ESIGN, matter management and billing, retrieval-augmented legal AI, court-filing integrations and eDiscovery pipelines with redaction. Attorney-client privilege, ABA Model Rule 1.6 and EU professional-secrecy duties stay engineered in, not bolted on. SOC 2 Type II progress and ISO 27001 readiness underpin every engagement.
Challenges
The legal challenges we solve
Legal teams buy software under a specific kind of pressure: every workflow touches privileged data, cross-border e-signature and filing rules differ by jurisdiction, and generative AI is arriving faster than most firms can govern it. We turn each of these into engineered controls rather than after-the-fact policy — delivered through AI, ML & data and software modernization engineering.
Ungoverned legal AI
Hallucinated case law and unsourced answers are a malpractice risk, not a demo bug. We ship retrieval-augmented assistants with citation enforcement, evaluator harnesses and human-in-the-loop review.
Cross-border signing validity
A signature valid in one jurisdiction can be challenged in another. We build to eIDAS QES/AES in the EU and ESIGN/UETA in the US, with identity binding and court-defensible audit trails.
Manual document & contract work
Partner time lost to redlining and assembly is margin lost. Clause libraries, conditional templates and playbook-driven CLM move routine drafting off fee-earners without losing control.
Fragmented matter & billing data
Matter, time, trust and disbursement data scattered across tools breaks conflicts checks and LEDES e-billing. We consolidate them into one auditable system of record.
Court-filing & eDiscovery burden
e-Filing portals and discovery obligations differ per court and per matter. We integrate PACER, CM/ECF, Tyler EFM and e-CODEX, with OCR, privilege detection and chain-of-custody redaction.
Our LegalTech practice serves four buyer profiles: AmLaw and Magic Circle firms modernizing matter management and billing; in-house legal teams building contract lifecycle and self-service workflows; ALSPs delivering managed services on top of automated review and eDiscovery; and LegalTech vendors building products on Clio, NetDocuments, iManage or custom stacks. We engineer under eIDAS for EU qualified e-signatures, ESIGN Act and UETA for US signing, ABA Model Rule 1.6 on confidentiality, EU professional-secrecy duties, ISO 27001 readiness and SOC 2 Type II progress. HIPAA controls apply to firms handling PHI in healthcare law. Explore how we deliver this through our SaaS Development service.

Compliance
Regulations and standards we engineer to
GDPR-aligned · ISO 27001 ready · SOC 2 Type II in progress · eIDAS-ready · ESIGN/UETA · HIPAA-capable
ABA Model Rule 1.6 (confidentiality) Attorney-client privilege EU professional-secrecy duties eIDAS (QES / AES) ESIGN Act UETA GDPR CCPA / CPRA ISO 27001 SOC 2 Type II HIPAA (healthcare law) EU AI Act (justice-administration AI) NIST SP 800-53 NIST SP 800-171 (federal contractors) LEDES e-billing
We treat these as engineering requirements, not paperwork: controls are designed into the data model, pipelines and release process. This page frames them as legal-vertical challenges — for the implementation detail on individual regimes, see our dedicated GDPR compliance consulting, SOC 2 readiness, HIPAA-compliant development and EU AI Act compliance services.
Practice areas
Legal practice areas we build for
Workflow, privilege exposure and integration needs differ sharply by practice. We tailor the data model, retention schedule and AI guardrails to each area rather than shipping a generic case tool.
Litigation & disputes
Matter timelines, deadline calendaring, e-filing to PACER/CM/ECF and state portals, and eDiscovery with privilege detection and chain-of-custody redaction.
Corporate & M&A
Contract lifecycle management, clause libraries, virtual data rooms, due-diligence review with legal AI and playbook-driven negotiation workflows.
IP & patents
Docketing with statutory deadline logic, prior-art search assistants, portfolio dashboards and renewal-fee automation across jurisdictions.
Immigration & conveyancing
High-volume, form-heavy practices: intake automation, conditional document assembly, status tracking and client self-service portals.
In-house & legal ops
Self-service contract requests, approval routing, spend and matter analytics, LEDES e-billing and outside-counsel management.
Personal injury & healthcare law
PHI-aware case management under signed BAAs, medical-records ingestion and OCR, and HIPAA Security Rule safeguards on top of legal-matter security.
Tech stack
The LegalTech stack we build on
We standardize on a security-first, AI-native stack and integrate with the systems law firms already run — iManage, NetDocuments, Clio and the major e-filing portals — rather than forcing a rip-and-replace.
Application & APIs
TypeScript, React and Next.js on the front end; Node.js, Python and PHP/Symfony services; PostgreSQL and event-driven APIs behind a documented, versioned contract.
Legal AI & RAG
Retrieval-augmented generation with pgvector or a managed vector store, citation enforcement, evaluator harnesses and human-in-the-loop review. Models run in dedicated tenants or on-prem when matter data cannot leave the firm.
e-Signature & identity
eIDAS qualified trust service providers, DocuSign/Dropbox Sign and native QES/AES flows, identity binding, KYC onboarding and remote online notarization where US states allow it.

What clients say
Remote document signing is a legal minefield. YuSMP built both the mobile signing flow and the Symfony CRM in a single engagement, handled KYC onboarding, and delivered API docs that our compliance team cleared in days.
A retail chain with dozens of locations needs document workflows that non-technical staff can follow without training. YuSMP built an internal DMS with approval chains, versioning, and role-based access that our compliance officer called the cleanest system we have ever deployed.
FAQ
LegalTech FAQ
Do you build to eIDAS qualified e-signature standards?
Yes. We integrate qualified trust service providers under eIDAS, support QES and AES levels, and design audit trails that hold up in EU member-state courts. For US flows we deliver ESIGN Act and UETA-compliant signing with parallel disclosures.
How do you protect attorney-client privilege in software?
We isolate privileged matter data with tenant boundaries, encryption with customer-managed keys, redaction tooling for eDiscovery and access logging that supports ABA Model Rule 1.6 and EU equivalents on professional secrecy.
Can you build legal AI with retrieval-augmented generation?
Yes. We deliver RAG over firm document repositories with citation enforcement, evaluator harnesses, hallucination tests and human-in-the-loop review. Models run in dedicated tenants or on-prem when client matter data cannot leave the firm.
Do you integrate with court filing systems?
We integrate with US e-filing systems including PACER, CM/ECF and state portals through Tyler EFM, File & ServeXpress, OneLegal and TurboCourt. For EU we support e-CODEX and national portals on a per-jurisdiction basis.
How do you handle SOC 2 and ISO 27001 for legal products?
We engineer to SOC 2 Type II controls from day one — change management, access reviews, vendor risk, incident response — and align with ISO 27001 Annex A. We deliver evidence packs that shorten client security reviews.
What about HIPAA for healthcare law practices?
For firms handling PHI in personal injury, medical malpractice or healthcare regulatory work, we operate under signed BAAs, isolate PHI tenants and apply HIPAA Security Rule safeguards on top of standard legal-matter security.
Do you integrate with iManage, NetDocuments and Clio?
Yes. We integrate with the document and practice-management systems firms already run — iManage, NetDocuments, SharePoint, Microsoft Word and Clio — through their APIs, so automation and legal AI work on top of your existing document estate rather than requiring a migration.
Can you build white-label LegalTech products for vendors and ALSPs?
Yes. We build LegalTech products for vendors, ALSPs and legal publishers under your brand — multi-tenant SaaS with per-client isolation, usage metering and SOC 2 evidence packs your buyers can review. You own the IP and the roadmap.
How do you handle EU AI Act obligations for legal AI?
AI used in the administration of justice can fall into high-risk categories under the EU AI Act. We build for it: documented data governance, logging, human oversight, transparency notices and risk management. For the full framework, see our EU AI Act compliance service.
Do you support on-prem or private-cloud deployment for sensitive matters?
Yes. When client matter data cannot leave the firm, we deploy on-prem or in a private cloud (VPC) with self-hosted models, customer-managed keys and no third-party data egress. We scope the deployment model during architecture, not after go-live.
How do you handle data residency for EU and US matters?
We pin storage and processing to the required region — EU data in EU regions, US data in US regions — with data-residency controls in the architecture, GDPR-aligned transfer mechanisms and per-tenant configuration for firms operating across both.
What does a typical LegalTech engagement look like in cost and timeline?
We start with a two-week fixed-scope discovery and a written diagnosis, then build in two-week increments behind feature flags. A focused module ships in weeks; a full matter-management or CLM platform runs across months. We size budget and timeline against your practice map after discovery.
