Canonical Question of Jurisdiction

Pondering the canonical relationship between parishes, pastors, and permission to marry outside one's parish, I asked this question of Father Zuhlsdorf, the famous blogger [his emphasis]:

I hope this finds you well! My question: if one is a registered member of a territorial parish in whose geographical boundaries you do not live, is it necessary to receive permission from your “territorial pastor” to receive the Sacrament of Matrimony in some other parish?

This seems to be common practice in my diocese, with an argument made that the “pastor of registration” has the care of that person’s soul, rather than the “territorial pastor,” thus rendering the permission of the pastor in whose geographical boundaries you live unneccesary.
