Advice needed please

Hi,

I (the Petitioner) have contacted the courts this morning regarding my divorce petition. They have not received an AoS still from the Respondent.
This is the third time the courts have posted the Petition out to his address. However he has stopped all contact with me since Feb time and I have no way of getting in contact with him or through anyone else due to him working and living somewhere in Pakistan. The courts advised me to request deemed or dispensed service.

Dispensed as I understand is when the Petitioner has tried everything possible to get hold of respondent and has no contact details etc, is this correct? I do have his contact details but he is ignoring me so I would be rejected this request straight away most likely...

Deemed service - is this when the respondent acknowledges in some way as having had got the petition? I don''t have this as he is not responding to any of my messages, email or phone calls... So again I can''t really use this method either can I?

Is it worth me requesting dispensed or deemed service, can they both be done in the same application or do they have to be done separately?

Unfortunately I can''t afford a lawyer as I being made redundant currently but I really want some advice on what option is the best for me, it has been over 6 months now since the divorce proceedings started and this is mentally exhausting. If he only responded to me then things would be much simpler but he is the type who runs off and doesn''t look back to help or sort things out

What grounds are you using in the Petition?

I am using UB grounds.
