The operating system of the succession law firm. Traceable. Verifiable. Signed.
The professional platform for lawyers, estate partitioners and notaries. Manage clients, mandates, succession cases and judicial partitions with full traceability, eIDAS signature and integrated CRM.
Why succession law firms lose time and clients
Without CRM, clients are lost
Leads arrive, are managed via email or WhatsApp, and then disappear. Without a clear pipeline, firms lose mandates every week.
Family conflicts over everyday assets
The mere presence of the grandfather's watch triggers impossible negotiations. Without a structured process, conflicts become entrenched.
Weeks of calls and emails
Coordinating three heirs for a simple decision takes longer than the negotiation itself. The chaos of communication exhausts everyone.
Lack of transparency in distribution
Without a clear and documented process, each party believes the other is gaining an advantage. Distrust blocks agreements.
Signatures delayed indefinitely
Obtaining signatures from all parties becomes a project in itself. One heir is always travelling.
Chaos of Excel, PDFs, and emails
Without a centralised system, traceability breaks down and defending the process against a subsequent challenge is nearly impossible.
Lex Partis solves all of this from first contact to final deed.
Try 14 days freeThe right process for every inheritance
Every succession is different. LexPartis offers four specialised types, each with its own phase flow, documents and validations.
Full Succession (Integral)
The complete succession case, with or without a will (testate or intestate): from the post-mortem moment through to the definitive distribution of all assets. Covers the entire process — opening, inventory, valuations, tax settlement, partition and delivery — with full traceability at every stage.
- Testate and intestate cases, common and regional law
- Full inventory, valuations and inheritance tax (ISD) settlement
- Partition and notarial ledger with asset allocation engine
- Full traceability of every decision and document
Judicial Partition of Inheritance
For cases involving conflict between co-heirs or under judicial supervision. Complete management of the court-directed inheritance division procedure (LEC arts. 782–805): from preliminary steps to judgment, notarial protocolisation and tax settlement.
- Pre-litigation, registered letters and lawsuit
- Counter-partitioner operations and partition ledger
- Procedural incidents, resolutions and appeals
- Notarial protocolisation and registry registration
Distribution of Household Effects
For family distributions of personal and sentimental items without formal valuation. Fast, consensual and documented.
- Inventory without mandatory appraisal
- Distribution by lots with family consensus
- Family distribution certificate
- Fully adapted for sentimental objects
Out-of-court Agreements
For cases where, within ongoing judicial proceedings, the co-heirs reach agreements on the allocation or distribution of specific assets, avoiding a court ruling on those particular points.
- Partition ledger by agreement of the parties
- eIDAS signature on all consensus documents
- Guided process without mandatory conflict phases
- Documentation ready to be elevated to a public deed before a notary
From death to adjudication
A step-by-step guided flow for the lawyer, the notary and the heirs. No missed steps, no missed deadlines.
Open the case
Register the deceased, the heirs and the title to succession (will or intestacy declaration). LexPartis automatically assigns the legal phases and deadlines.
Inventory and valuations
Add assets, debts and charges. Manage expert valuations, registry certificates and inheritance tax (ISD) settlement with all documents linked.
Partition and ledger
Prepare the partition ledger: forced-share calculations, collation, allocation lots and monetary compensations. The partition engine detects indivisible assets and suggests legal solutions.
Sign and close
Documents are signed with eIDAS electronic signature. The file is sealed, audited and ready to be elevated to a public deed before a notary.

LexPartis generates the partition deed in PDF format ready to be executed as a public deed.

Each case file has a deadline tracker tied to the date of death. The system automatically alerts before the voluntary ISD period expires (6 months) and before the extension deadline (another 6 months), indicating the competent body for each autonomous community or regional treasury.
