Forming separate and joint possession
In some cases, more than one noun is possessive.
Determine if the possession is separate or joint; i.e., does the possession apply to each party separately? If so, it is separate possession. Add the sign of possession to each.
This requires the doctor's and the patient's signatures.

The Jones' and the Browns' houses were for sale.
NOTE: Repeating the with each name emphasizes the separate ownership.
If one or both of the names are replaced by a possessive pronoun, reword the sentence if necessary to prevent awkward phrasing.
D: my and the patient's signatures
T: the patient's and my signatures
BETTER: the patient's signature and mine
D: their and our benefit
BETTER: their benefit and ours
To determine if there is joint or common ownership, look for shared possession; i.e., do both parties have possession.
Add the appropriate possessive sign to the final name alone. If one of the owners is identified by a pronoun, make each name and pronoun possessive.
