Thanks for you question.
I think you are probably right to be concerned.
Surprisingly, there is a bit of a grey area over whether a beneficiary has a right to see the Will. Ultimately, the Will shall become a public document once the grant of probate has been obtained (it will be attached to the grant) so there is little reason to withhold it. Though there may be some circumstances in which the executors postpone, for example where the beneficiary is to inherit subject to surviving 28 days from the date of death then they will likely wait until the 28 day period has expired.
If you are concerned (it sounds as if you should be) that there may have been some undue influence with respect to the execution of the Will in hospital then I would advise two things:-
1. Immediately make a "standing search" of the probate calender, which will notify you and send you a copy of the grant if one is taken out within 6 months of the date of the search:-
This will keep you in the picture with the administration of father's estate
2. Go and see a local solicitor, tell him your concerns and get him to write a letter to the executor on your behalf asking for the issues to be address by your brother in law. Take a copy of the Will passed to you by your brother in law.
It does all sound quite fishy and there may be a reasonable explanation as to why your brother is obfuscating but I think you could benefit from formalising things by getting specific legal advice since it should hopefully compel your brother in law to provide some clarity over the situation. It really is a situation that a professional should take over for you, contentious (disputed) probate is much better handled by a practitioner rather than a lay person. If nothing else, it will quicken the resolution of the issues and provide you with some interim peace of mind.
