Dad finally agreed to let someone deal with the limb over the driveway. Good. Do not spend that small victory on a one-line estimate that says "tree work" and leaves every expensive noun for later.

The useful question is not whether the price looks reasonable. It is whether two strangers could read the signed paper and agree on what the crew must do before asking for final payment.
Start by identifying the exact tree
Walk the property with Dad and the estimator. Put a simple identifier in the quote: front-yard maple beside the driveway, rear oak near the west fence, or marked tree shown in the attached photograph. If several trees are involved, number them on a sketch or photograph and use those numbers throughout the contract.
Then make the paper distinguish removal from trimming. "Trim tree" does not say which limbs come down, how much clearance is expected, whether deadwood is included, or whether the crew may reshape the whole canopy. If Dad only authorized removal of the limb over the driveway, write that. A general permission to trim is a poor substitute for a marked photograph.
Ask who makes the call if the crew discovers decay, a split union, an occupied nest, or another condition that changes the proposed work. The answer should be a pause and a written change order, not an additional cut followed by an additional charge.
Make the ground work part of the job
Tree removal can mean cutting the trunk near grade and leaving everything below it. Stump grinding is a separate operation unless the contract says otherwise. If grinding is included, the paper should state which stumps, the intended depth or result, and what happens to the grindings.
Do not let "cleanup included" carry the whole load. Ask whether the crew removes logs, limbs, chips, sawdust and grindings. Ask whether it rakes the lawn, clears the driveway and sidewalk, and removes debris that falls into a neighbor's yard. If Dad wants usable firewood left behind, state the approximate length of the pieces and where they will be stacked. "Leave wood" can otherwise produce a new obstacle course beside the garage.
Write down who repairs ruts, broken fence sections, damaged gutters, cracked paving or torn lawn caused by the work. The point is not to predict every mishap. It is to prevent the contract from treating foreseeable access damage as Dad's surprise.
Name the route into the yard
The quote should identify where trucks, a lift, a chipper and workers may enter. Check gate width, overhead wires, soft ground, sprinkler heads, buried pet fencing and the septic area if there is one. Mark places the crew may not drive or stage equipment.
If access depends on moving Dad's car, opening a locked gate or using a neighbor's property, settle that before the crew arrives. Permission to work on Dad's tree is not permission to occupy somebody else's yard.
Ask the contractor who handles any required permission for street occupancy, traffic control, utility clearance or work in a public right of way. Requirements vary by municipality and by the location of the tree. Put the responsible party in the contract instead of relying on "we usually take care of it."

Separate proof of insurance from the promise to be careful
Ask for a certificate of insurance sent by the insurance agency, not merely a photograph of an old certificate in the salesperson's phone. Check the insured business name against the name on the contract. Ask whether the coverage is in force for the planned work and whether workers are employees, subcontractors or both.
A certificate is information, not a guarantee that every loss will be covered. If the job involves a large tree, a crane, utility lines or substantial neighboring property, Dad can call the listed agency and ask what the document confirms. If the company will not identify itself consistently on the quote, payment request and insurance paperwork, stop there.
Control additions with a change order
The contract should say that extra work requires Dad's written approval before it begins. A change order should identify the added or deleted work, the change in payment and any change in the work window.
This matters when a crew is already in the yard and someone says another limb "really ought to come down." Dad can say yes. He can also say no. The paper should preserve that choice instead of turning a conversation near a running chipper into a disputed authorization.
Do not sign for Dad unless you actually have authority to do so and intend to use it. If Dad is the customer and can sign, the contract should carry his name. You can help compare the documents without quietly becoming the person who owes the bill.
Read the cancellation paper before treating it as an escape hatch
A contract signed at Dad's house may qualify as a home solicitation sale, but the legal definition and exceptions matter. Missouri law gives a buyer a cancellation right for qualifying home solicitation sales and requires specified contract language. It also limits cancellation when the buyer requests immediate emergency performance and the seller makes a substantial start before cancellation (Missouri Revised Statutes sections 407.700, 407.705 and 407.710). The federal Cooling-Off Rule also covers certain sales made at a home or another qualifying location and requires cancellation disclosures (Code of Federal Regulations, title 16, part 429).
Do not tell Dad that every home contract can automatically be cancelled. Check where and how the deal was made, whether it was a qualifying solicitation, whether emergency work was requested, and what notice the contract provides. If cancellation is being considered, preserve the signed agreement, cancellation forms, envelope, messages and proof of delivery. This is general information, not a conclusion about Dad's particular contract.
Close the lien question with paper
Missouri's mechanic's lien law expressly reaches landscaping services, and lien rules can involve contractors, subcontractors and suppliers (Missouri Revised Statutes sections 429.010, 429.013 and 429.016). That does not mean every tree-work disagreement creates a valid lien. It means "Dad paid the salesperson" is not the only fact worth recording.
Before final payment, ask for a final invoice showing the agreed work and approved changes. Ask the contractor to identify every subcontractor and equipment provider whose bill could affect the property. Request the appropriate final lien waivers when the work and payment justify them. Missouri law prescribes requirements for an unconditional final lien waiver involving residential real property, so do not improvise the form or ask someone to sign it before payment has actually cleared (Missouri Revised Statutes section 429.016).
If a lien notice, demand letter or disputed waiver appears, preserve it and get Missouri legal help for the specific facts. The statute references used here are collected through the site's Sources page.
Make the warranty answer four plain questions
If the contractor promises a warranty, have the contract state what is warranted, what remedy is offered, how long the promise lasts, and who must be contacted. A promise that a removed tree will stay removed is not much of a warranty.
Useful warranty subjects might include completion of the specified cuts, removal of listed debris, repair of contractor-caused damage, or return to grind a specifically included stump that was missed. Check exclusions for weather, hidden underground conditions, decay, insects, utility work and damage attributed to preexisting conditions.
Also ask whether a warranty request pauses any payment deadline or whether Dad must still pay the undisputed part. The contract should not force him to guess how to report a problem.
Hold final payment for a daylight walk
Set the payment stages in writing. Tie final payment to completion of the named work, cleanup, removal of equipment, delivery of the final invoice and any required closeout papers. Avoid a clause that makes the whole balance due merely because a crew arrived or began cutting.
Walk the property with Dad in daylight before the final payment. Use the marked photographs and contract, not memory. Check each tree, stump, debris area, fence line, driveway and equipment route. Photograph anything unfinished and send one written list to the contractor.
Tonight's move: put the estimate beside a blank sheet and write five headings - tree, cuts, stump, cleanup and damage. If the estimate does not answer one of them, send the contractor the missing questions before Dad signs or pays a deposit.
