What can I do about a domestic violence charge with no witness or medical records?

The police reports and medical records do help to corroborate your claim of domestic violence if your case is going to trial. One thing you should keep in mind however: Now that New York State allows No-Fault divorce, if your ultimate goal is to obtain a divorce from your husband, then you may want to consider proceeding on a no-fault case. This is because in New York, the grounds for the divorce will often times have very little impact on the ancillary matters such as maintenance, equitable distribution, and other related matters dealing with the financial aspect of the case. So if you are finding it difficult to proceed on the grounds of cruel and inhumane treatment, but still want to get divorced, then I would recommend adding a second ground of no-fault to proceed.

Beatings result in physical damage that is easily documented with photographs. If it was one incident I could understand you not documenting it but you refer to it as 'beatings' as in a routine or at least more than one time occurrence. There is no question your failure to document these incidents will be used against you in your divorce case. However, you don't need someone to witness the actual beating if you have anyone who can testify to seeing the physical damage after the beating that may help. Of course if there was no physical damage, you may want to down grade the term beating to verbal or mental abuse.
