Absolute worst experience. First started off with promises of finishing divorce and child custody fast & easy. I had already filed most of my paperwork and was already towards the end of my case until we got in court and my ex partner didn't want to agree to anything so instead of fighting to get the trial finished fast my "lawyer" didn't say a word and we got pushed back 3 times all while still collecting money for absolutely no work.
Went to mediation and came to an agreement myself. He missed a hearing and his response was "I didn't know you had court today"

Still being charged when he did not show up. Every time I call in to his office his receptionists are very rude even arguing with me about who is right and who is wrong.
Finally had to sub him out and do it all myself as I should have done from the beginning.

For the thousands I have to pay and to get nothing done I Would HIGHLY NOT RECOMMEND!

Dear Matthew Edward Sheasby:

I want to express my deepest gratitude to you. In the property lawsuit with my ex-husband, your unremitting efforts have won the greatest guarantee for me and my children.

From the moment the case began, you showed extraordinary legal knowledge and keen insight into details. You not only listened to my appeal carefully, but also patiently explained the complex legal procedures, which gave me a clear understanding of the whole litigation process, because you made me see hope in the most difficult days.

In court, your eloquence is impressive. You are not only defending me, but also fighting for my future and the future of my children. Your every word and every argument is full of strength and faith, which makes me feel deeply at ease. Your efforts finally helped us win this lawsuit, which is not only a legal victory, but also a guarantee for our future life.

I know that behind the victory of this lawsuit is your countless days and nights of hard work and selfless dedication. Your professionalism and persistent pursuit of justice make me have a deeper respect for the profession of law and lawyer. Your success is not only due to your legal skills, but also because of your compassion and deep care for customers.

Here, I would like to say to you: Thank you! Thank you for your help, thank you for your support, and thank you for everything you have done for our mother and daughter. This letter can't fully express my gratitude, but I hope it conveys my respect and gratitude to you.

Please accept my most sincere thanks and wish you a prosperous career, and you will continue to bring justice and hope to more people.
