Divorce or separation can be painful for mums, dads and children - but the split often has a traumatic effect on grandparents too.

Recent figures show an average of seven grandparents a day are applying to the courts to win contact with their grandchildren, often when an acrimonious relationship break-up has led to one parent refusing to let their ex-partner's parents see the children.

Government figures show that in 2013/14 there were 2,517 applications for contact by grandparents, compared with 2,319 in 2011/12.

Marilyn Stowe, a senior partner at Stowe Family Law, which has offices around the country, says the figures are shocking. She points out that grandparents don't have an automatic right to contact their grandchildren following a separation or divorce, which is why they end up going to court.

"My granny was my best friend growing up, and the idea that I might have lost contact with her if my parents had divorced is unimaginable," she says.

"But that's what happens to many grandparents. The Government statistics are shocking and it's long past time family members had legal rights, subject to what's in the best interests of the child."

Stowe says that in most cases it's the paternal grandparents who face losing contact, sometimes because access is used as leverage to gain ground in other areas such as better maintenance payments, or perhaps because the child's mother feels they're interfering in the child's life.

She explains that because grandparents don't have any legal right to see their grandchildren, they have to apply for leave to be heard by the court, and this has to be granted before they can apply to see their grandchildren. Such applications were previously called Contact Orders, but have now been renamed Child Arrangement Orders.

"Grandparents have a huge role to play in a child's development," says Stowe. "They give them a sense of family history and can help them shape their identity as an individual.

"Discovering that they might have to go to court to ask for permission to see their grandchildren is a real shock for many grandparents, and in some cases they won't pursue the matter for fear of causing even more trauma for their grandchildren."

Stowe says that mediation is a better option than court, although many grandparents don't realise that court isn't the only avenue available.

"It's very sad because a solid relationship between a grandparent and grandchild can be a real lifesaver for a struggling child in the unsettling time during and after divorce," she says.

She strongly advises grandparents to maintain "scrupulous neutrality" during the divorce proceedings, treating their child's partner with respect from the start.

She adds: "However difficult things become, criticism of the partner, especially to their grandchild, is absolutely a no-go area.

"Their grandchild should feel like grandparents provide a non-judgmental bolthole, and if grandparents stick to their neutrality, they have a much better chance of being involved in the child's future."

Lynn Chesterman, chief executive of the Grandparents' Association, says that having seen her own child's relationship break down with two very young children caught in the middle, she knows it's vital for grandparents to bite their lips when it comes to taking sides in the divorce or separation.

"It's your natural instinct to stick up for your own child, but in the middle of it there are confused grandchildren. You have to breathe and count to 10 before you comment on anything to do with the break-up," she advises.

"Make yourself the safe place for the grandchildren to come and talk about anything. The only way they'll feel they can do that is if you don't take sides. It's really difficult and it has to be a conscious effort, because it goes against everything you want to do."

Chesterman says the Grandparents' Association supports many grandparents who go to court to gain access to their grandchildren, either because of their children's relationship break-up, or family feuds.

"In all cases, we advise that court should be the last resort," she says, pointing out that as well as the upset any legal action may cause, legal aid isn't available so it's likely to be an expensive process.

"Get it sorted out for the children's sake, and try everything else before court, even if it means apologising to a parent about them being upset," she advises.

However, she acknowledges that some grandparents will do anything to be able to see their grandchildren again.

"Grandparents tell us that not being able to see their grandchildren is like a bereavement," she says.

"To have a big input in their lives and then to lose it suddenly is horrendous."

As well as legal action, some grandparents will even adopt subterfuge to try to see their grandchildren - Chesterman recalls one case where a grandmother put on a burkha as a disguise so she could stand outside her grandchildren's primary school to see them.

"You can understand why people think it's the only way," she says.

"But mediation is the best way, so if you're offered the chance, take it. Even if the other side won't do it, the fact that you've offered to do anything and everything to see your grandchildren looks good in court, if that's what it eventually comes to."

ASK THE EXPERT

Q: "My friend's young daughter has just been diagnosed with a terminal illness, and I don't know what to say to her. What's the best way to help?"

A: Heather Tilley, a family support and bereavement counsellor for the Shooting Star Chase children's hospice charity, says: "Having a child diagnosed with a life-limiting condition is every parent's worst nightmare, and serious life-changing events can make or break friendships as we often don't know what to say or do.

"Friends can help by first of all staying in touch - don't avoid the family. They need their friendships to remain stable otherwise it's another loss they have to deal with.

"Think before you speak. Parents often feel vulnerable, and insensitive comments can compound those feelings, however well-meaning.

"Listening is much more important than what you say or do - being there is invaluable and can make a real difference.

"Sometimes the parent may not want to talk or even see their friends. You're not a mind reader so simply asking if they fancy a chat is best.

"Often parents are reluctant to ask for help, and being specific about it can feel very supportive. So you might offer to pick one of their other children up from football, for example. But don't take over - always offer choice.

"Talk about your life. Parents are still interested in what's happening in their friends' lives - sometimes it can be a helpful distraction. Just avoid the trivial small talk.

"Don't stop inviting parents to social events, but be understanding if the invite is declined, parents cancel at the last minute or need to leave early.

"Remember the dads. Often the focus for support and friendship will be on the mother but fathers also need opportunities to talk."
