It is my understanding that only one parent needs to agree to the filming while the parents are still married. Also, only one home owner needs to give permission for the film crew to be on site while they both own the home.
Jon is a tool of epic proportions.
Oh, and Discovery network, who owns TLC, has offices in DC.
depends on how property ownership is defined and limited where you live.
if there's are ccr's or local/state laws that were in place when a person purchased that create a specific definition and empowerment/limitations to "owners" it can require any/all persons with titled interest (and in some cases those under contract to purchase) to come to 100% agreement. this is the case where we live-and we've got a situation where one owner thought so long as he got at least one spouse from each household to sign off on a permit issue he was free and clear-NOPE, none of the signatures except those that done by single owners are deemed legaly valid (and the one single owner he got was under contract so those new owners have gotten that one invalidated

not sure what the filming laws are where the gosselins live, but our kids have attended schools that do filming for promotional purposes and they have always required both parents (married or not) singatures on the permission/releases (only if a person can show they have sole physical AND legal custody can they go with just one).
with the complaints from some of the gosselin neighbors that have been printed in some publications regarding the traffic and the papparazzi i'de be curious to know what the zoning is in their neck of the woods-it looks to be a lovely rural area in which case a commercial buisness being conducted on the property might be illegal-in which case it would'nt be an issue of who wanted it vs. who did'nt (and since there are episodes with kate talking about how that home was ideal because it had space they could earmark for the crew and their equipment it would be a hard argument to say it was'nt in part purchased specificaly for the purpose of doing the show).
