Joint Tenancy + Ownership Agreement


Frequent Poster
Can & does an ownership agreement similar to the draft agreement in the below key post apply to Joint Tenancy or does it only apply to Co-Ownership?

My partner & I are currently buying a house together, we intend getting married in the near future & have chosen Joint Tenancy as our ownership type & instructed our solicitor accordingly. We see value & practicality in having an ownership agreement in place also. Any advice or experiences welcome.
