What gets files rejected

  • Probate authorities usually require the death record and the heir list issued recently.
  • Asset descriptions must match the registry entry rather than an informal description.
  • Spell every name exactly as it appears in the passport, across every document in the same bundle.
  • Never remove staples or separate pages that an authority has bound and stamped across the seam.

What this certified set is used for

  • Overseas probate applications
  • Transfer of inherited assets
  • Bank and insurance releases

Talk to us before you commit to anything

Many clients arrive with one set of documents while the destination expects a different one. We start by asking where you are filing, for what purpose, and by when — then tell you plainly what is required, including the steps you can complete yourself at no extra cost. A team with over 15 years in cross-border documentation is available before you spend time on the wrong route.

  • Destination requirements explained in plain language.
  • A clear statement of which steps your case needs and which it does not.
  • Help sequencing multiple documents across multiple authorities.
