With sites that have been purchased in perpetuity, responsibility for the site, or ownership, passes to the purchaser’s next of kin in accordance with his/her last Will. It is in essence treated like any other asset but without monetary value. The inheritor then assumes responsibility for the site.
Often the purchaser of a gravesite is someone other than the deceased and usually this person is named as the “Applicant” on the cemetery’s burial order. As an “asset” the responsibility for the site passes to the Applicant’s beneficiaries or next of kin.
If you want to take responsibility for an older gravesite and particularly if you want to renovate, reuse or undertake any monumental work, you need to search for the direct relative of the person responsible for the grave (the Applicant), or the next of kin who is the main beneficiary to the Applicant of the grave in question. If you can’t locate a direct descendant, the cemetery may accept a statutory declaration stating that you have made attempts to find the appropriate descendant and that you are the next of kin with “authority of all concerned”.
If you are successful in “adopting” the grave you will become legally responsible and this responsibility would then be passed on to your main beneficiaries.
If you find that the burial information is incorrect you can have the cemetery correct the record by providing certified proof (say a death certificate) with the correct information. This does not mean that the cemetery will correct any headstone errors. To change the monumental work you will have to be or become officially responsible for the site.
