The emigrant generation built the South-East's most characteristic cross-border estate: a life's savings and a house in an English city, and the home farm or a site never let go in Kilkenny or Carlow. One death opens two administrations, because neither country's grant operates in the other, and the families who handle these estates well are the ones who grasp early that they are running two processes that must be choreographed, not one process with a complication.
Which grant leads
The usual sequence runs from domicile: the estate is proved first where the deceased was domiciled, and the second jurisdiction's application is grounded on court-certified copies of the will and the first grant. An Irish-domiciled deceased with English assets proves here first, then applies there; the London-domiciled emigrant with the Kilkenny farm reverses it. There is no resealing between Britain and Ireland, each grant is a full application, but the second is substantially administrative where the first was properly done, and the two administrations can overlap far more than they usually do.
The friction points
The predictable snags are documentary and financial: institutions in one country querying documents executed in the other, identity and verification requirements for personal representatives abroad, currency movement between estate accounts, and the doubled professional cast, solicitors here, solicitors there, each needing the other's paperwork. Post-Brexit the underlying law is largely unchanged but the administrative friction is real. The cure is parallelism and a single point of coordination: this practice runs the Irish side and the timetable, with the foreign lawyers fed what they need when they need it.
Tax and distribution
Both jurisdictions' tax regimes may touch the estate, and relief arrangements exist between them; nothing should be distributed from either administration until the position in both is confirmed, and specialist tax advice should be obtained in each jurisdiction. The drafting lesson for the living is equally clear: anyone holding assets in both countries should take advice on whether one will or concurrent wills serve their estate better, because the answer differs case by case and the wrong structure adds months to both administrations.
