The devolution decision, inheritance shares, a complete estate inventory and available valuation records should be kept together. For real estate, add a land-register extract, plans, encumbrances and a current valuation. For vehicles, works of art or company interests, document ownership, condition, market value and any third-party rights.
Each co-heir should also record which asset they would take, which alternative they accept and what equalisation they consider appropriate. A clear schedule prevents the proceedings from focusing on one asset while other values or debts remain outside the calculation.
