What does deforce mean?
To deforce is to wrongfully keep someone out of property they are legally entitled to possess — most often land — whether by physical force, threats, or simply refusing to give it up. The word belongs chiefly to the vocabulary of law: in historical English common law, an action of deforcement lay against anyone who held lands against the true heir's claim. The term remains alive in Scots law today, where deforcement names the distinct crime of physically obstructing or resisting an officer of the law in the execution of their duty, such as a bailiff enforcing a decree or a constable making an arrest. Derived forms include "deforcement" (the act or the legal remedy) and "deforcer" (one who deforces). Because it so closely resembles the far more common "deforest," readers encountering it should note the very different meanings. Precise, forceful, and unmistakably legal, deforce is a useful word for describing dispossession backed by power rather than right.
To wrongfully withhold possession of property, especially land, from its rightful owner or occupier, typically by force or exclusion.
"The trustees alleged that the cousin had deforced the rightful heir from the family estates."
Chiefly historical in English law; still current in Scots law.
(Scots law) To obstruct or resist a person performing a lawful duty, such as an officer serving process or making an arrest.
"Interfering with the sheriff's officers constituted deforcing them in the exercise of their duty."
The corresponding offence is called deforcement.
The wrongful withholding of property from its rightful possessor; the act or fact of being deforced.
"The writ complained of the long deforce of the manor by the neighbouring lord."
Rare; more commonly expressed by the derivative noun "deforcement."
As a noun denoting instances of wrongful withholding, the plural applies when referring to multiple such acts.
"The record listed numerous deforces of tenant lands over the preceding century."
Though nearly extinct in modern English law, "deforce" survives as a living crime in Scots law — physically resisting a bailiff or police officer can still get you charged with deforcement.

Etymology of deforce
Deforce entered Middle English from Anglo-Norman and Old French deforcier, formed from the prefix de- plus forcier, "to use force," itself derived from Latin fortis, meaning strong. It thus shares its root with words such as effort, enforce, reinforce, and fortress, all built on the Latin idea of strength. The term took on its specialized sense of forcibly withholding property in medieval land law, where deforcement named both the wrongful act and the legal action brought against it. While obsolete in modern English law, the verb and noun survive actively in Scots legal usage for resistance to lawful authority.
