My ex and I are still continuing with contact as normal. We have an existing court order in place. Unless one household is self-isolating due to somebody having symptoms, we will continue to abide by the court order.
But then we’re also in the middle of another court case (last hearing was in Feb, next due in May) about those arrangements, and any non-compliance with the court order without having very good reason, or any attempt to manipulate the current COVID-19 situation, would be looked upon very badly.
I’ll add that the logic behind the government allowing children to travel between their 2 households is to maintain some sense of normality for the children. At a time where their schools are closed, their activities cancelled, and they can’t visit other family or friends, maintaining contact is at least some degree of normality for them - the same as children who live full-time in just one household have.
In addition, if you don’t have a court order now, you’re very unlikely to get one any time soon. I guess maybe unless you both find solicitors taking on new clients, come to an agreement between yourselves, and get the courts to approve it. But that’s likely still take months, and if it’s that easy you wouldn’t need a court order.
Even in normal circumstances the entire process is many, many months. We’re now a year into our current case. I’ve still not had confirmation that our next hearing will go ahead next month (remotely or otherwise), and there are valid safeguarding concerns substantiated by the police and school.
