GOO LUCK!

Why not "ownership"? It is just what you mention in your question.
Hope it helps!

We used to say the account holder or the securities holder back when I traded

Good luck,
Claudia

Depends on how formal/legal you want to be, and on your sentence. See these example sentences indicating usage:

The Chairman shall hold the title to the shares in the name of....

Title in the shares is reserved to the holder and immediate family members....

John holds shares in .....

I say title, because to 'own' refers to something concrete (a house , car etc).

And 'hold' is synonymous to 'own' but is more appropriate of paper that represents an ownership. It's more usual as a verb.

PS Keith: if you gave contextual sentences it would be far easier than for contributors to be trying to double guess and think of a range of synonyms!

Titular is an adjective that means: of, pertaining to, or of the nature of a title.The noun is TITULARIDAD. TITULARIDAD= TITULARITY.
(The word is of Latin origin).

The word "Titularity" is not listed in any dictionary. I think we had better check if the word exists in English first through a monolingual dict.before suggesting its use...
