Facing domestic violence charges isn't an easy feat. You have to think carefully about which defense options will apply to your case. This means that you must consider the factors of the incident to determine your defense strategies.
One of these is that you can claim that there is no proof that you were violent toward your partner or spouse. You will have to make the jury question whether the prosecutor's case is believable. If the jury convicts you, the jurors must believe that you committed the crime beyond a reasonable doubt. Being able to make them question any element of the prosecutor's claims might result in a not guilty finding.
Another option is that you acted in self-defense when the situation got out of hand. This might be feasible if you had marks on you at the time of the incident. Witnesses might also be able to help substantiate your version of the events.
You might be able to claim that your accuser made false accusations against you. This is a challenging situation to be in because you must do this in a way that doesn't make it seem as though you are attacking the victim.
Claiming that you had consent to behave violently, such as in the case of a fetish, might be feasible in some cases. Another defense is that they have the wrong suspect.
No matter what defense you decide to use, it is imperative that you start planning the strategy as soon as you find out that you are facing charges. This helps you to avoid having to deal with a defense that seems rushed.
