Reflexive possessive pronouns
Reflexive possessive pronouns, for example sitt, deras, and ert, also describe ownership but refer back to the subject in the clause. Many find it difficult to know whether to use sin/sitt/sina or hans/hennes/dess/deras.

What is the difficulty?
The reflexive possessive pronouns are used when you are talking about something that belongs to the subject in the clause.
Emil träffar ofta sina kusiner. / Emil often sees his cousins.
Here we are talking about Emil's cousins. The pronoun "sina" (his) refers back to the subject (Emil) of the clause.
Emil träffar ofta hans kusiner. / Emil often sees his cousins.
Here we are talking about someone elses cousins. The pronoun "hans" (his) refers to someone else.
A few more examples:
