Quit Claim and survivorship

[Cheryl James]

I'm buying two parcels. I am planning on getting quit claim deeds for ease and expediency. 

The previous deed has the name of two dead parents and the son with rights of survivorship.  

If a new quit claim deed is created and filed, what issues could arise? Is having copies of death certificates on hand enough? Can death certificates be filed with the deeds?

Thanks!
