Work Injury Claim Private Investigators

Work Injury Claim Investigations

In cases involving workplace accidents or suspected fraudulent injury claims, our private investigators gather evidence to support or dispute injury-related reports. We conduct discreet surveillance, verify medical activity, and document the claimant’s physical condition to assist companies, insurers, or legal teams in reaching a fair and accurate outcome.

Child Custody Investigations​

In Singapore, child custody is one of the biggest concerns during a divorce. The court determines which parent will be given the authority to care for the child and make major decisions regarding the child. It also gives the custodial parent the right to make decisions and judgments regarding the matters of the child, such as the child’s education, health conditions, daily affairs, and so on. 

Private investigators are also hired to look into critical family situations in which child custody is involved. In such a situation, the parent of the child should hire a private investigator to investigate the living conditions and provision of care and concern towards the child, to find out if he or she is capable of providing and ensuring the well-being of the child. Such evidence is very crucial in winning custody of a child.

The use of private investigators to gather evidence in court is vital in civil cases such as divorce and child custody. In such situations, the evidence provided by the private investigator determines who wins the case.

Divorce lawyers and private investigators. Didn't ever think of using them, but when times call for it....

That being said, Ace assisted me in my time of need. Provided timely updates and gave a sense of assurance that when service was requested they were on hand at a moment's notice.

Easy to understand fee and service structure. Clear report provided. Even though evidence was sufficient, continued to provide support to conclude the hours quoted for.

Also gave some helpful advice on how to proceed further with the information they have gathered.

The most important thing about any service is the assurance that someone is supporting you and working with you. It does not matter how big or how small your request is. This is what Ace Private Investigations had provided me.

I felt a sense of support and that someone is listening to my problem. The solutions provided was only possible with the dedication from Ace and I felt I did not have to worry about handling things by myself. Definitely deserving of a good service award.
