"After 25 years of marriage I personally went through a very difficult divorce while my boys were still young. I have personal experience with this subject and will do my best to get you the answers and proof needed to help your case."
Alimony Alimony arrangements can be infuriating when the alimony recipient secretly cohabitates with a new partner. Often times, this will result in one of two untenable situations: the alimony recipient may be using their alimony disbursements to financially support the new partner; or the alimony recipient may be receiving cash payments of financial support from the new partner, while concealing significant changes in their own finances.

Co-habitation is an area where divorce and dissolution become extremely messy. The obligor (person making the payments) sometimes hires a private investigator to monitor the alimony recipient and try to prove co-habitation. If in fact co-habitation is discovered, the obligor may follow up by trying to discern the financial changes that result from the new cohabitation arrangement. The evidence obtained often yields a complete picture of the situation, which is then used to persuade a judge that cohabitation is occurring and an alimony modification is warranted.

Pre-Marital Investigations

In today’s fast paced world of dating, the rules have changed and with the myriad of on-line dating services and sites, not everyone is who they say they are. Blackstone Investigations Group can perform comprehensive background investigations to make sure your new date (or that of a loved one) does not have anything in their past they aren’t revealing. Sometimes that bad feeling about a loved one’s significant other is completely justified. Find out the truth for your peace of mind and to protect your future.

Family Matters

Child Custody/Child Support
Child Support The welfare of children is always of utmost concern. In a divorce situation or separation, the parent awarded custody may not be suitable as the primary care giver. In some cases, even visitation may not be appropriate. The other parent may have started dating someone with a questionable past or possible criminal background, or may be using a baby sitter who might not be fit to care for your children. BIG can inconspicuously follow a parent during their planned visitation to determine if any illicit or inappropriate activity that is happening while your child is in the other parent’s care. Our investigators can also follow and videotape the other parent on their own free time to document and investigate their lifestyle, daily activities, living conditions and persons they associate with.

A change in circumstances may also warrant a change in child support payments. If you suspect that the award of the court ordered child support did not accurately reflect the other parent’s ability to pay, or that the financial circumstances of that parent have changed for the better, BIG will document the necessary evidence of lifestyle, income, and assets needed to build a case to substantiate your claim.
