Is there any sort of pre filing checklist on here that we should follow before filing? Just curious. Here is my plan so far.

Please be brutally honest on anything I should change/revise/add/remove/etc.

Brief summary...42 yrs old, STBX is 38. We have 2 young kids, ages 3 and 1. They turn 4 and 2 this July. Washington State (Snohomish County). Married in 2019.

Housing. Do not move out. I understand the logic behind this. We currently live in a rental house that my STBX's parents own (we live right next door to them). There is no formal rental agreement in place. I understand that this is still considered a marital residence and by law I would not need to move out unless ordered by a court....however, let's say when I do file, that her brother and dad (and likely uncle that lives 30 seconds away) would come over and threaten me if I refuse to leave. Do I call the police at that point? Would her parents owning the house and not having a rental agreement in place sway the police to say hey, you need to leave? Because I am pretty confident that this is how it would go down. Update I asked this during a consultation with a divorce attorney and was told that they can legally evict me since there is no formal rental agreement in place. However, I also reached out to an eviction law/services place, and was told that since because there is no rental agreement in place, that I would not be a tenant, and you have to be a tenant to be formally evicted. They said that the in laws could take me to court but it would be pretty lengthy and expensive. And as I was advised on here previously, any court order that would have me leave I would respond with by filing an injunction. Basically I intend to do everything in my power to NOT move out of the house.

Finances. Discussed this too during attorney consultation. Bulk of our funds are in a joint savings account (around $485k. This includes around $300k profit from the sale of my condo and around $100k profit from the sale of her house). Was told since the funds are co-mingled in a joint account that the account will likely (though not necessarily) be split 50/50. In hindsight this was a huge mistake on my part, but it is what it is at this point. My plan is to purchase a house using a down payment consisting of my half of these funds along with an additional $50k pulled from my 401k (the max I'm allowed to withdraw since divorce does not qualify as a "hardship" according to T Rowe Price) and additional funds (around $40k I have in an IRA I inherited from my Dad when he passed that she is not entitled to). Alimony/spousal support. Right now she makes close to what I make (a little less as I just got a 5% raise at work). This topic as well was discussed during my consultation, and I was advised that there is a strong possibility that since we both work and make close to the same amount and have only been married since 2019, that any alimony would be minimal and likely not last more than a year if that. I consider this a small victory but feel free to tell me if I'm being misinformed here. PS...I have opened up my own solo account to move funds over when the time comes right before I file.

Belongings. I've taken photos of everything in the house and made a written inventory. How would I go about determining the cash value and replacement costs? Would an appraiser do this? Hiring one before I file would be the best plan I assume?

Parenting/Journal. My boys are my world but I've made an extra effort to spend as much time with them as I can lately, be as actively involved and try to lead in terms of parenting. I've been keeping a journal for months to demonstrate being SuperDad (again my boys are very little so sports, school drop offs/pickups, extra curricular stuff hasn't factored in yet, although my oldest is in soccer once a week, so I definitely go to that every time). Will be plotting this all to a chart soon and have it boiled down to the following topics: Meals/food, Safety, Play, Teaching/Encouragement/Discipline, Day to Day. Open to suggestions here though if anyone feels I should change this. I tried checking a couple months back for a good parenting class to take but have not found one that I want to commit to yet (admittedly I've been slacking on this). In terms of child support, I have not yet filled out the detailed worksheet as I need to determine what the STBX's gross income is, but using the quick calculator based on the fortress.wa.gov website, it works out to about $1200/month, though I want to pad in a bit more just incase so will be ear marking $1400/month as mentioned earlier.

Witnesses. I have no family in the area, which definitely isn't helping in coming up with witnesses to vouch on my behalf. I do have some friends that I've known for years (pre-marriage) that are married and have kids of their own that I plan on asking to help with this however, as we've had play dates, birthday parties etc where they have seen me with my kids. My oldest is in pre school, and I know some of the other parents there and will be asking them as well, though they are good friends with the STBX, so I won't be able to count on their support, but no harm in asking.

Safety/CYA. I have a DAR that I run 24/7, although the battery is starting to lose strength so I'll be buying a backup recorder just in case I run into any issues where I'm around the wife and one of them stops working. My .357 handgun is at my friends house to hang on to, as I've read on here it's NOT a good idea to keep that in the house when she could make bogus claims against me involving that.

This is where I'm at so far. Anything glaring that I am missing and should be doing (or not doing?)

Any and all advice/suggestions are appreciated.
