What do you mean by rotating savings and credit association? We don’t use that terminology in the UK.
By rotating savings, is this a scheme where, say, 20 people put an amount of money into a pot each week or each month and then, each 20th week or each 20th month, each of them takes the pot? Is that what you are thinking of?
What do you mean by a credit association?
It would assist us if you could explain your situation in detail please.
I’m afraid that writing letters from solicitors practices is not a service this website offers. If you want that, you will have to consult a high street firm of solicitors who will then deal with it on a time cost basis and they would usually need you to go in to see them and are likely to charge several hundred pounds for the advice.
We can give you the advice you are looking for but it would only be in the form of this exchange.
Do you want to continue on that basis?
