I am happy to help.
As a grandparent, as you don't have an automatic right to contact, you have to file for permission to apply to court first. If you apply, the court will consider your connection (if any) to the children; the nature of the application (the reasons why) and whether the application would be prejudicial to the child in any way. There would be a hearing which you will need to attend you would have to persuade the court that there is a meaningful relationship with the child and that you benefit the child's life. The court will also weigh up whether if it makes a contact order, would this affect your relationship with the child's parents and any other family members who might object.
Before applying to court however, it's best to try mediation as this is normally a requirement of the court.
You can find a mediation service here:
If this doesn't work, and you do need to go to court, this is what you would need to do -
You need to file the C2 form for permission, along with the C100 which is going to set out the contact that you would like to have with your grandchildren.
Both can be sent on the same application and the court fee to do this is £215.
You can possibly get a fee exemption if you are on low income/have low savings. You would need to fill out a fee exemption form (http://www.gov.uk/get-help-with-court-fees)
I hope that this helps. It's always so difficult when families fall out but the children should not be the ones to suffer and the court will promote contact if it is in the child's best interests.
Do remember that I can only give you my opinion.
Another lawyer may have a different opinion. If there was a black-and-white answer to every legal problem there would be no need for anything to ever proceed to court!
