HELP:How do I file a petition of recognition of foreign divorce Judgement

I married an Australian Citizen we were married here in the Philippines. My Ex wife has filed a divorce in Australia and it was granted. I have the copy of the divorce order with me it was sent by the Australian Family Courts via email and it has an electronic signature.. Now is this enough to present to the court when i apply for a recognition of foreign judgement? If the court ask me to prove its authenticity since it was only sent via email whee do i go to have it authenticated?

2nd what are the steps to file a petition of recohnition of foreign judgement. Do i get a form to fill in? Does my application need to go through an attorney? Or I can do it on my own? how much is the filing fee if theres any? And what do i expect when im done filing an application.. Atty. I hope you can help me oit with this so i can prepare.. I really wanted to sort this out. I can never tell i might marry someone again and i want everything legal. Thanks in advance

imo, that electronic copy will not be admissible because it is not authenticated.

you are going to need a lawyer.

Atty if electronic copy will not available what else should i provide to satisfy the requirement?

I mean if electronic copy is not enough what else do i need to provide to support that divorce order?
