What is the current system?
People wanting to donate their organs after their death must sign the NHS organ donor register, or their families must agree to their organs being donated.
So what is being proposed in Wales?
Ministers want to change the system to one in which people opt out rather than opt in. They say it will drive up transplant rates. Currently, 266 people are awaiting transplants in Wales. The change will create two forms of consent in law – the "deemed consent" of those people who have not registered to opt out of donating an organ, and the "express consent" of those who have registered to say they wish to be a donor.
How will they know who wants what?
A single register will be created and record whether or not someone wants to be an organ donor. Donors will also have the option to donate certain organs but not others.
To whom will the new law apply?
Everyone over 18 who has lived in Wales for the past 12 months.
What about families' wishes?
The Welsh health minister Mark Drakeford has promised to give families a "clear right of objection". And he has also said any organs will not be taken unless a family member is present.
But what if a family does not know what their loved one wanted?
In this case, the default position is the deceased was in favour of donation and, as a matter of law, the deceased's consent is deemed. Relatives will be told that the deceased had not opted out, and had made no further wishes known.
So, in that situation an organ will definitely be donated?
In theory, no. Although the family has no legal veto, the last decision will ultimately rest on clinicians – who have a duty not to add distress to families of someone who has died. Even if it passes that stage, clinicians have a range of other factors to take into account.
When is the new system due to start?
Once given royal assent, the law will come into effect from 2015. Ministers need to launch a two-year publicity campaign to alert people to the changes
