How do I no what solicitor is best and won't rip me off
Difficult question to answer. Starting point would be to identify solicitors in your local area that specialize in Family Law. Most solicitors will give 30 minutes free consultation. During this time you can ask them what their charge rates will be. Compare several before choosing.
For information my divorce was completed in 2016. Solicitor charged 175/hour. Barrister charged 400/hour.
As to what the final cost would be that will depend on the conduct of the 2 parties. If both are upfront with disclosure and tell their Solicitor the full and true story and aim for an amicable settlement it will cost a lot less than if one, or both, make the divorce a contest or try to hide details of earnings, assets, pensions, etc,.
Depends on courts workload, but my solicitor advised 6 months to complete if done sensibly and amicably. Maybe 12 months or more if one, or both, are obstructive.
In my case it too almost 2 years. Ex was super obstructive. Marriage certificate disappeared soon after I filed for divorce. My Ex was the applicant for the Financial Order and jumped from one solicitor to another, failed to comply with Court Orders for disclosure, etc. All came out in the end as Judge at Final hearing soon realized who the trouble maker had been. Most of my legal costs had to be borne by ex and was reflected in final settlement. So ex effectively shot themselves in the foot by being awkward.
