The point you might have trouble with here is probably the section “sin perjuicio de”. Right? If so, I suggest two possible translations, one sticking strictly to the legalese speak and another one a bit more flexible.

Translation in full (legalese version):
(…) sin perjuicio de que se disponga la resolución del contrato.
(…) without prejudice to the termination of the contract.

Alternative option (you might have to rephrase the full paragraph a bit, I think):
(…) sin perjuicio de que se disponga la resolución del contrato.
(…) and will not affect the possible termination of the contract.

Here an example of the first reading, but UK English:
http://www.banksidecommercial.com/wp-content/uploads/2016/03...
Without prejudice to the termination of the Agreement today, or to any rights flowing from that termination, (…)

This excellent link explains clearly how this expression is used in the UK and the USA:
http://www.adamsdrafting.com/without-prejudice/
“Without Prejudice”
(..)
The phrase without prejudice would seem a product of the same bureaucratic instinct that gave rise to notwithstanding the foregoing. You’d be better off omitting it or using something simpler. For example, instead of shall be without prejudice to, you could say will not affect.

It is up to you to decide if you want to use strict legalese (which I recommend in these cases despite the opinion expressed before) or to resort to a more flexible use of the language.

As for the term “resolución”, even though it is not primarily the point in this query, I recommend “termination” instead of “cancellation”. See here:
