Hopefully your parents will have made a Lasting Power of Attorney and will have made a Will. If not, it is very important to get these documents in place as soon as possible. Elderly parents can find discussing these subjects quite difficult and they might refuse point blank to even consider them! It might help if you can offer some examples of how helpful having these documents in place can be. Give a couple of scenarios where it would be difficult for you to act for them without a Lasting Power of Attorney in place and also how important it is for them to make a Will so that their wishes are followed after death. Keep talking and hopefully they will see that this makes sense.
