Yes the defendant can be called to the witness box to serve as an evidence to the facts stated by him/her, but there is a procedure that needs to be followed.
If the defendant has pleaded not guilty, he/she must submit evidence in support of his/her statement, and the court will need to hear evidence from witnesses in order to decide whether the defendant is guilty or not. After the other witnesses have been cross examined, the lawyer of the defendant must depose the defendant himself as a witness. He will then be examined in chief by his own lawyer first and after the examination in chief is done, the opposing party’s lawyer can cross examine him.
In this particular case of dispute over property, since you have stated that the defendant has provided false facts, he/she will also have to submit evidence supporting the facts stated by him/her and this includes entering the witness box themselves.
