This is fairly wordy...the second sentence in particular is mostly unnecessary (the ordeal makes him a better man is pretty much the arc we would assume).
Should the attorney be 'successful'? If he was, we might be more inclined to think he should be able to deal with this ordeal, so the struggle would not be so great. Perhaps it might be more of a challenge if he was a 'struggling' attorney? Or perhaps he is a 'selfish' attorney and the ordeal gives him perspective about the importance of family?
Here is a suggestion which may have some use:
"When a struggling attorney returns home for his mother?s funeral to find his Alzheimer?s-stricken father is suspected of her murder, he must wage the case of his life to save his family - and himself."
Also the title seems strange - it's not about the judge is it, it's about the lawyer and/or the case. Perhaps it could be called "The judgement" or.....?
Cheers
