Divorce attorney

Made math errors while having all the detail that cost me thousands of dollars. Promised to meet me for the closing and never called. Then shared that the Judge made his decision and the closing wasn't important. I watched the other side press an outstanding closing and not leaving a stone unturne...d. He told me the Judge doesn't like you. Several attorneys later explained it had to do with the delivery and the closing is as important, LAZY!

Dave and his team are a caring, compassionate, and knowledgeable group that helped us get through a difficult family case.

The Real Deal!

I really don't know where to start...I have been working with Dave for about a year regarding my case. From day one, he has been open and honest. He gave me great advice and always tried to save any expenses. For Dave, it's not about the money, it's about doing what is right and I truly cannot tha...nk him enough!

The BEST Divorce Attorney in NJ!

I met with a number of attorney's regarding my divorce. As soon as I met with Mr. O'Sullivan I immedately felt a level of comfort that I hadn't experienced at any other consultations I previously had. Mr. O'Sullivan was extremely attentive as I spoke about my situation and had a number of great su...ggestions and offered concrete advice as to how he would handle my highly complex case. Mr. O'Sullivan's knowledge of the laws amazes me . His level of integrity, honesty and professionalism are second to none. When he needs to fight, Mr. O'Sullivan fights hard and aggressively -- he always gives 110% in all that he does and gets RESULTS! No matter what time I reach out to him, Mr. O'Sullivan responds immediately -- he makes himself available to discuss any issues (major or minor) I may have. He always makes me feel as though I am his only priority (even though I know how busy he really is). Mr. O'Sullivan has an outstanding reputation amongst other attorneys and is extremely well respected and highly regarded whenever I mention his name and see him interact with his peers.. Thus far, I have been extremely pleased with the level of service and the results that Dave has achieved with regards to my ongoing, and highly contentious divorce. I have the utmost faith and confidence that he will succeed in getting me the most favorable and positive result at the end of this litigation. Having Dave guiding and representing me was the best decision I made. I would highly recommend David T. O'Sullivan to anyone looking for an attorney, especiallly a divorce attorney.

Bankruptcy isnt easy, but he made it easier for me.

Mr. O'Sullivan was a huge help through my case. I know that would be his job, however he made me feel secure through the process, always kept me up to date and was a terrific guide through it all. I was scared and helpless, and he helped me through a difficult time, when I wasn't sure how to get out ...of my debt.I couldn't have done it without him. Thank you.

Divorce and separation lawyer | Feb 16

Relationship: Opposing Counsel on matter

"David and I were adversaries on a very contentious and financially complex divorce. David was incredibly proficient at the nuances of determing the value of a business as well as cash flow of the litigants. It was a pleasure working with an attorney who understood the complex financial and tax issues presented in high net worth divorce. David is agressive but not unreasonable which is a valuable combination in the divorce arena."

  • Experience & background Years licensed, work experience, education
  • Legal community recognition Peer endorsements, associations, awards
  • Legal thought leadership Publications, speaking engagements
  • Discipline Disciplinary information may not be comprehensive, or updated. We recommend that you always check a lawyer's disciplinary status with their respective state bar association before hiring them.
