This might help with the rules where there is no will
“If the deceased’s estate is less than £270,000, the full estate will go to the spouse or civil partner, and only this person will be entitled to take a letter of administration. In the case that the estate value is higher than that, then the first £270,000 will go to the spouse, and the rest will be divided in two between the spouse and the children. In such case, the children and the spouse can apply to take a letter of administration”
I read this as if the amount of assets your Dh left (don’t forget if your name is on the deeds as well as your dhs then your Dh only left 50% of the value of that property after mortgages etc have been deducted not the whole 100%) after mortgages etc have been deducted, the first £270,000 of cash or assets go to you.
Then the remaining amount you divide by 2. You get one half of the amount and your ds’s get to divide the other half between them.
It is like on a divorce. Everything is given a valuation less mortgages etc. Except you can take £270,000 and half of the remainder.
I.e. on a £1million pounds of assets left by your Dh spread across for example 5 properties of £200,000 each which were solely in your dh’s name
You are entitled to the first £270,000 then half of £730,000. So in total £635,000
So you can take 3 properties, your sons can take a property each but then have to pay you £35,000 (£17,500 each) in cash or they can jointly own 1 property and the other property is sold and you take the £35,000 from that and your ds’s will divide the remaining £165,000. (Less expenses)
Having given POA to a family member and being royally screwed by someone close. I would never do anything that handed control over to anyone else no matter what they promised.
I would actually see a solicitor and ver tjis. A few hundred in legal advice could save yours and your ds’s relationships and you a lot of money.
