Forced marriage is haram and invalid:
A young girl came to the Prophet (peace and blessings be upon him) and told him that her father had married her off against her will. The Prophet (peace and blessings be upon him) gave her the choice to either stay married or walk away from it. (Abu Dawud)
The majority of scholars derived from this that the contract cannot be nullified because it never even existed. Imam Abu Hanifa (rA) saw that it would become valid if the girl approved. Either way, no scholar has ever allowed forced marriages in Islam.
