I found three canons in the Code of Canon Law that seem to appy to your question:Canon 1061 §1 A valid marriage between baptised persons is said to be merely ratified, if it is not consummated; ratified and consummated, if the spouses have in a human manner engaged together in a conjugal act in itself apt for the generation of offspring. To this act marriage is by its nature ordered and by it the spouses become one flesh.
Canon 1142 A non-consummated marriage between baptised persons or between a baptised party and an unbaptised party can be dissolved by the Roman Pontiff for a just reason, at the request of both parties or of either party, even if the other is unwilling.
Canon 1681 Whenever in the course of the hearing of a case a doubt of a high degree of probability arises that the marriage has not been consummated, the [marriage] tribunal can, with the consent of the parties, suspend the nullity case and complete the instruction of a case for a dispensation from a non-consummated marriage; eventually it can forward the acts to the Apostolic See, together with a petition, from either or both of the parties for a dispensation, and with the Opinions of the tribunal and of the Bishop.
