Yes, a deed of variation can still be made even if a beneficiary of the estate has died, but it may require the consent of the deceased beneficiary's estate. The remaining beneficiaries can agree to change the distribution of the estate as long as they follow the legal requirements. It's advisable to consult with a legal professional to ensure that the variation is valid and complies with relevant laws.
