This will depend on the legal constitution of the PPL/VPL rightsholder member entity (for example a sole trader, partnership or limited company) and any local laws that might apply.
Further advice should be sought from the legal advisor who is preparing the will on your behalf.
If the rights are going to form part of your estate and you have a will, you may want to consider letting PPL/VPL know the details of your executor and making your executor aware of PPL/VPL.
