Step 2

Once my services have been formally retained—I will begin the process of curating all required legal documents.

Step 3

I will keep you updated and informed of your legal paperwork and court filings until case completion.



A Divorce legally dissolves a marriage and releases both parties from the responsibilities of their union. Ensure that you have a trusted attorney on your side to protect your legal rights, represent you in court, and negotiate your custody, visitation, division of property, etc.

Child Support

Child Support is court ordered payments typically made by non-custodial parents to the custodial parent or guardian, to contribute to their child’s needs. Parents have a legal obligation to financially provide for their children. Who is responsible for Child Support will vary dependent upon income levels, and full, shared, or joint custody. My goal is to ensure that fair and reasonable child support is achieved.


Clearly defined Visitation Schedules ensure that both children and parents enjoy quality time with one another. Children are often the ones caught in the middle of a failed marriage, and the Law Office of Sean B. Oster is here to advocate for your child’s best interests. Whether the goal is to gain Visitation or change visitation rights—your child’s well-being is the primary goal.

Maintenance (Alimony)

Spousal Maintenance payments provide ongoing financial support to a spouse after a marriage has been dissolved. Spousal Maintenance is sometimes referred to as alimony, or spousal support, and is awarded in addition to child custody. Standards of living can drastically change after separation or divorce, often leaving one of the two parties financially vulnerable.


Custody is the court ordered legal and/or physical right of one parent over the care, control, and maintenance of their child. Establishing conclusive Legal and Physical Custody is required to protect your rights as a parent, and more importantly, the best interest of your child. Custody Orders are legally complex and exceed full, shared, or joint custody, but also pertaining factors such as physical care, supervision, medical care, religious upbringing, and day-to-day physical care. Child Support will vary depending on income and custody levels. My goal is to ensure that both fair and reasonable Custody and Child Support are achieved.

Prenuptial Agreement

From a legal standpoint, marriage is a legally binding contract made between two adults. As a proactive approach to protecting current assets, future earnings, business ventures, property divisions, parental rights, etc., a prenup is required. Your Prenuptial Agreement will ensure that your expectations are clearly defined, and that your assets and interests are protected.


A Will allows you to take a proactive approach to protecting your family, your assets, and your intended plans for all that you have worked hard to accomplish. Appoint an Executor to manage your estate and distribute your property exactly as you wish. Appoint guardianship of your children in the event of an untimely demise. Ease your family’s stress by clearly defining your wishes, and bypassing the lengthy probate process that will ensure if a Will is not established.
Power of Attorney
A Power of Attorney allows you to select someone (your Agent) to manage your affairs on your behalf, or “act in your place” if permanently or temporarily incapacitated. If you do not specify your preferred Power of Attorney, your affairs could be left in the wrong hands, and your intentions for your assets and finances skewed. A Power of Attorney does not extend to health and medical care.
Health Care Proxy
A Health Care Proxy allows you to choose someone (your Agent) to make general or specific health care decisions on your behalf if you are temporarily or permanently unable to do so. If you appoint no Health Care Proxy, decisions are likely to fall on your next of kin. Appoint a Health Care Proxy, and ensure that your health care wishes are respected.
Living Will
A Health Care Proxy appoints someone to specifically manage your medical care in the event you are unable to do so. While a Living Will does not appoint a specific proxy, it allows you to outline your healthcare wishes in the event that you are able to speak or act on your own behalf. Reach out to me today to ensure that your medical care is managed with the dignity and respect you deserve.

Desk Appearance Ticket (D.A.T.)

A Desk Appearance Ticket (D.A.T.) is a written notice to appear in Court for Arraignment—where criminal defendants are formally advised of their charges and asked to enter a plea. D.A.T’s are often issued after an arrest for a Violation or Misdemeanor instead of being placed in jail. They are occasionally issued for Felonies. A D.A.T. must be taken seriously as it is not a get out of jail free card. The arraignment is only a first appearance in court, and jail time, fines, probation, community service, and more may follow.


Don’t wait until after your D.A.T to hire an attorney. Reach out to The Law Office of Sean B. Oster to secure quality legal representation!

Misdemeanors can include Public Intoxication, Disorderly Conduct, Vandalism, Simple Assault, Drug Possession, and more.


Non-Payment Proceeding

A Non-Payment Proceeding is a legal means for a Landlord to evict a Tenant for Non-Payment of rent.  Landlords cannot legally evict tenants without adhering to the Non-Payment Proceedings. If you are a landlord who requires assistance moving forward with an eviction, or a tenant who believes their tenant rights have been violated, please contact my law office today.

HP Action (Apartment Repairs)

Landlords must provide their Tenants with timely repairs and services, as laid out in your Lease. If a Landlord fails to uphold their responsibility, filing an HP Action will protect your Tenant rights. Landlords must provide you with a habitable residence, meaning the timely resolution of essential repairs is required. If your essential repairs have gone unresolved, an HP action will protect your tenant rights, as established by the State of New York.

Holdover Proceeding

Holdover Proceedings are a complex means of evicting a tenant for reasons other than Non-Payment of Rent. This could include lease violations, squatting, unauthorized pets, unauthorized subletting, unauthorized tenants, nuisance complaints, property damage, and illegal activity. If you are a Landlord who would like to evict a Tenant for reasons other than Non-Payment, or a Tenant who is wrongfully being evicted, please reach out today to discuss your Landlord/Tenant rights.

Evictions/Illegal Lockout

Landlords cannot lockout or evict tenants at their own volition. Eviction is part of a lengthy legal process, whereby Landlords must file the proper paperwork. I work with landlords to navigate the complex eviction process, and with tenants to ensure that grounds for eviction are sound, checking the formal process has been followed.
