    Asset researcher in estate matters


    We carry out asset research both within the Netherlands and abroad at the request of notaries, laywers and others. We also conduct research at the request of and provide aid to creditors [of an estate or an heir] by identifying assets belonging to the estate which may be sold in order to settle the claim. Asset research is essential, not least because it determines the tax base for inheritance tax. Executors and court-appointed liquidators are jointly and severally liable for the payment of inheritance tax.
