Criminal Defense

At Unity International Law we practice criminal defense law having both the knowledge of the procedure's and evidence laws required, in addition to our team of trial advocates whom are experienced with almost all kinds of criminal offences.

The Thailand Criminal Justice System is based on Western law and has both similarities and differences with the criminal law systems of other countries. Thailand law recognizes basic rights, including the right to a trial, the right to present witnesses and evidence to defend oneself, the right to an attorney, the right against self-incrimination, and the requirement of proof “beyond a reasonable doubt” of guilt. In general, the Thailand police have a certain degree of discretionary power to make arrests.  However, in recent years, amended constitutional provisions have provided for a system of regular judicial review of detention and searches made by the Thai police.

The Thai penal code enumerates a number of criminal offenses which may result in arrest and imprisonment in Thailand. In addition to the Thai penal code there are separate acts and laws which also provide for criminal penalties.

Normally, a criminal case begins with an investigation by the police, investigators from an administrative section of the Thai government or private investigators. Once enough evidence is established to file a criminal case, bail may be requested.  Bail amounts and conditions may be different for foreigners than for Thais.

Thailand does not have jury trails. In a normal criminal trial in Thailand, three judges are typically present. Orders of detention are viewed on a periodic basis when a defendant is in the pre-trial custody phase.

Some foreigners in Thailand find themselves having difficulty with the law for a variety of offenses including theft, assault, murder or business offenses, such as fraud and violations of various administrative acts and regulations. Additionally, many foreigners are also arrested for drug offenses, visa overstays and visa fraud.

Lawsuits & Disputes

The Importance of a Negotiation Lawyer

Lawyers negotiate constantly. Negotiations are used in various areas of the law to settle disputes. If you find yourself needing to settle a dispute, it is best to seek the advice of a Negotiation Lawyer.

Thailand has introduced a new law about negotiation or settlements before taking legal action. According to the amendment of the Civil Procedure Code (No. 32) B.E. 2563, the law states that “Before filing the lawsuit, the parties may request the court to appoint a mediator in order to settle the dispute.”

This new law functions as an alternative for the person who has a legal dispute and helps to settle the dispute before filing a lawsuit. As a consequence, clients may need to find a Negotiation Lawyer or a Settlement Lawyer in order to help them find the best settlement.

What is Negotiation?

Essentially, negotiation is the process where two or more parties seek to reach an agreement over something they have versus something that they want. The negotiation doesn’t always have to be over a physical item. Often times, services or statuses can be exchanged just as easily as objects can. Negotiations are used in various areas of law to settle the dispute, and often used in the settlement of contracts.

Negotiations are a good way for the two parties to sit down and air out their grievances and can help save on a lengthy trial or long litigation process. Therefore, negotiation procedures lead to a quick settlement.

Should I Ask for the Help of a Lawyer for Negotiation?

While negotiations are not lawsuits, it is best to seek the help of a lawyer should you find yourself entangled in the negotiation process. A dedicated lawyer can help assess your needs and evaluate your rights all the while ensuring you are protected.

If you find yourself needing assistance from a lawyer for negotiation purposes, reach out to the team at Unity International Law. Our team of lawyers are well versed and highly experienced.
