LegalMaster is a UK legal accounting and practice management platform built for the UK market — not Ontario LSO compliance, Canadian trust accounting, or Ontario practice requirements. Atticus is built from the ground up for Ontario law firms at $149 CAD per lawyer per month.
Atticus is a complete Ontario law firm platform — practice management, trust accounting, and Canadian AI built for the lawyers doing the legal work. Not a UK legal accounting platform requiring extensive reconfiguration for Ontario compliance.
LegalMaster is a UK legal accounting and practice management platform built for the UK legal market and UK Solicitors Regulation Authority requirements. Atticus is built from day one for Ontario law firms — LSO By-Law 9 trust accounting, Ontario Limitations Act 2002, HST billing, and CRA-compliant invoicing are built in.
Atticus includes trust accounting built specifically for Ontario LSO By-Law 9 compliance. LegalMaster's client account features are built for UK Solicitors Accounts Rules — fundamentally different from Ontario's LSO By-Law 9 trust accounting requirements.
Atticus AI is trained on Canadian and Ontario legal context. It extracts limitation dates, flags compliance issues, and answers practice questions — all integrated with your Ontario matters. LegalMaster has no Canadian legal AI capabilities.
Atticus stores your client data on Canadian servers by default, supporting LSO data residency expectations. LegalMaster is a UK platform — Canadian data residency is not available.
Atticus AI extracts key dates from client documents and applies Ontario Limitations Act 2002 rules automatically. LegalMaster has no Ontario limitation period tracking or Canadian legal deadline intelligence.
Atticus is $149 CAD per lawyer per month for complete Ontario practice management including AI. No UK platform import/configuration costs, no separate Canadian compliance tooling required.
See how Atticus compares to LegalMaster for Ontario solo and small law firms — complete Ontario practice management with integrated Canadian AI vs a UK legal accounting platform.
