You bring a case under those terms: "I am the legal owner of this land and I want the NFT which was owned by the deceased to be reissued to me". The legal binding on the original NFT is broken, and a new NFT is issued.
There's also provision under the UK Jurisdiction Taskforce digital dispute resolution rules https://lawtechuk.io/explore/ukjt-digital-disputes-rules to have an arbitrator use a judicial back door in the NFT contract to transfer ownership of the NFT if the contract has those affordances.
We feel that's very powerful.
