Buy from foreign seller, deceased, no will

[Gooberq Gob]

Im planning to but a house where seller is

A foreign national.

Deceased, without leaving a valid will.

Has a husband two kids, husband is not in US, one kid is in US, another foreign land.

In the Seller deed i see that seller had quoted a single, event though she was married and had two kids.

Will have any issue if i buy the property.

Title company is looking into the documents and asking for all sellers to be present at closing (Not sure whether they will all be there)

Do i have to worry about this ?

If Title company gives a title insurance , can i still buy this property or cancel contract.

Im worried that i might have issues down the road if i have to sell it.

Thanks in advance for advise
