The Kidney Wales Foundation, which was involved in the formulation of the 'opt-out' organ donor scheme in Wales, has stressed that family consent is vital.
All Welsh residents will be able to register their personal wishes regarding organ donation ... If you do not opt-in, or opt-out, if you do nothing, you will have deemed to consent to organ donation ...
Deemed consent donation will not go ahead in the absence of any family member.
Kidney Wales believe the presence of the family is essential - both as a source of necessary information about the potential donor and in order to ensure that donation does not go ahead in the face of the deceased's known objection to organ donation.
The Welsh Assembly has voted for a change in the law to try and save the lives of those who die while they wait for a transplant organ.
As Wales votes on changes to organ donation, ITV News speaks to those for and against the changes.
