Lasting Power of Attorney - DIY online

[ShipwreckSunset]

Has anyone any experience of setting this up themselves rather than using a solicitor? How did you find the process?
I think I may need to do this for my parents in the near future (health and financial) and wondering if it is something I can do myself rather than involve solicitor. The process outlined on gov website looks relatively straightforward.
If you did use solicitor, roughly how much was it?

Another point of view... we tried to buy a house a few years ago. The owner had dementia and had gone into residential care. The son had done one of the lasting powers of attorney and was arranging the sale of the house.

Except the son hadn't done it properly. The whole thing was a legal, tangled, mess with the sister of the son with the POA challenging the sale, constant back and forward to court. Unsurprisingly, we eventually pulled out.

So I would say it is well worth paying a professional to set it up for you. Legal challenges and fixing it will cost you a lot more if you get it wrong.
