Which documents do you need when separating?

Start with the legal relationship and existing agreements

First find documents describing the legal starting point: marriage or registered partnership, marriage or partnership terms, a cohabitation contract and earlier written agreements. A lawyer can explain which official copies or extracts proceedings require. The content and recency of documents depend on the selected route and specific case.

Keep original documents separate from your summaries. A note about what you once intended is not the signed contract. Record when an agreement was made, who signed and whether later changes were documented. Foreign documents may raise questions about language, origin and validity. Have actual requirements assessed first.

Create a four-column document register

A useful register can list document, date, purpose and missing information. For example, do not merely file a mortgage statement under housing: note which debt it shows at which date. This lets an adviser see whether it answers questions about current monthly payments, value or final settlement. Different questions do not always use the same documents.

Clearly mark whether an amount is confirmed, estimated or still needs checking. Do not change a source file to match your calculation. Keep a separate working copy for annotations. A good register saves repeated questions and makes discussion checkable without requiring you to give documents a legal valuation yourself.

Organise income and expenses without assuming an outcome

Collect relevant income records, tax documents and an overview of fixed expenses. For variable income consider the period each document covers. One good or bad month does not automatically give a complete picture. Business owners often need different records from a regular payslip; discuss appropriate information with the lawyer or financial expert.

Also show what is actually paid for children, housing, insurance and debts. This helps formulate a question but does not determine maintenance or division. For shared payments record who pays how much and under which arrangement. Tax effects and benefits may follow separate rules; your own list is not a Tax Administration decision.

Keep housing, assets and debts separately identifiable

Ownership documents, mortgage details, a current valuation and contribution agreements may matter for a home. For rented housing the tenancy agreement and named tenants matter. A monthly payment does not independently establish ownership or tenancy, and an estimated value does not yet determine the legal settlement.

For assets and debts note origins and agreements as well as amounts. Gifts, inheritances, personal contributions and joint loans can raise specific issues. Do not reach a final conclusion solely from the registered name. A professional can assess documents alongside the applicable marital property law, contracts and possible exceptions.

Create a separate practical section for children

Collect existing parenting plans, care arrangements, orders and relevant authority information. Add a preparation overview of school, childcare, ordinary care periods and recurring child costs. A practical calendar can explain the facts but does not replace formal assessment of authority or a court decision.

Do not share medical or other sensitive information more widely than necessary. A professional should explain what is relevant to the purpose and how to deliver it securely. A child need not carry papers between parents or prove which parent is right. Safety concerns may require different support or a special approach.

What if an important document is missing?

Record exactly what is missing and why it seems relevant. Ask whether a copy can be requested from the issuing body or professional who drafted the agreement. A lawyer can explain what may be needed through proceedings. One missing document does not automatically prevent starting a meeting or preparation.

Do not obtain missing information by logging into someone else’s account or changing a file. Keep your own correspondence requesting information. Distinguish a document still in transit, disagreement over its contents and refusal to provide relevant data. These situations may need different follow-up steps.

Deliver a focused initial set and manage versions

Ask the professional which initial documents are needed. A short case description, main questions and organised selection are often more useful than unsorted photos and messages. Follow the agreed secure delivery route. Do not put passwords or complete case files in a general website contact form.

Later record which version was discussed and what remains open. When a new statement arrives, note changes rather than invisibly overwriting the old one. A document register supports follow-up too: calculations become traceable and temporary arrangements can be checked against current information. Legal interpretation and choices remain tied to your case and the professional involved.

Practical checklist

• Create a register listing document, date, purpose and missing information.
• Collect contracts and orders without presenting summaries as originals.
• Separate income, fixed costs, housing, assets, debts and child matters.
• Mark estimates and outdated information.
• Ask which official extracts and recency are required.
• Agree a secure delivery route and recognisable version names.
