Inheritance query, too late?

[Whatnowmydears]

DH is an only child. Years ago after his DF died his mother quickly got a new boyfriend who moved into her home a couple of months later and the boyfriend then blatantly tried to alienate mother and son.

MIL was always a total narcissist, horrendous to DH, me and her grandchildren. New boyfriend encouraged this, even helping to drive a wedge between her and her life-long best friend too. Eventually DH went NC with his mother, as did her friend.

We recently randomly found out MIL died two years ago. Didn’t expect the boyfriend to try to contact DH to let him know, he’s sitting pretty in DH’s family home.
Probate has been granted and the solicitor who actioned MIL’s will didn’t try to contact DH either, perhaps they didn’t even know she had a son.

As far as we can see from the probate entry, MIL didn’t marry the boyfriend as it states her as still having her and DH’s family name.
Does this mean DH, her son, was still her next of kin?

Probate shows the boyfriend was an executor of her will, along with a neighbour we have never heard of. From the Land Registry, we can also see boyfriend is now the owner of the house.

So, basically, how do we get to see the details of MIL’s will? She may well have willed the house to boyfriend, or been in a civil partnership, but we just don’t know.
Is it too late for DH, her only son, to contest this?

Is it possible it went to court? Or if he purchased the property from the crown?

Lists of Demario’s I hope you get it sorted.

Thanks again to everyone for your advice. I think perhaps FIL’s will may be the key here. Need to unearth his will and proceed from there, if we can time wise.

@whatnowmydears if his will was probated it will be on the govenment will registry. Do you know if it was probated? If not and it is lost then only the first 250 k ( now 270 but it would the the old amount) of the house would go to MIL. Half the remainder would go to you husband. If fil and mil not married everything to your husband. These rules are for intestacy of if a will is not probated and lost.
