Are ECC-eu a creditable organisation to do my timeshare relinquishment?

Can you give me any information on Fernando y Associados based in Palma

I am the executor of an estate following a death.

My client had a French timeshare with Clubhotel and I understand that there is a French law where whoever inherits it can cancel the timeshare within 2 years of that inheritance.

My client died on 27 February 2021 and the estate is now ready for closing.

My client had very little in possessions and the small amount of money he had in the bank did not require probate to be granted to access it.

My client was receiving maximum UK benefits during his last 10 years of life including guaranteed pension credit.

There was no specific person to inherit the timeshare in his will and the person who would naturally inherit it would be his 77-year-old son who has Parkinson’s disease and other complications. Dealing with this timeshare problem in the next 18 months could create enough stress to shorten his life.

I would be grateful for some guidance as to how to deal with this problem.
