Diemer & Wei, LLP

Focus and practice areas

Diemer & Wei, LLP is a San Jose law firm that has run since 2003. It represents businesses and individual clients, and it handles matters in state, federal and bankruptcy courts. The firm sorts its work into business disputes, bankruptcy, real estate and employment, and it also practices telecommunications law.

That spread points to a practice built around commercial life in Silicon Valley. Companies form, sign contracts, borrow money, hire staff and sometimes fall out with the people they went into business with. The firm's four main areas track those events fairly closely. In my opinion, the mix reads as a general business practice with litigation at its center.

How the firm handles business disputes

On the business side, the firm takes on business dissolution, contract disputes, partnership and shareholder disagreements, fraud claims and unfair competition. These are the arguments that tend to surface when a company grows quickly or when it winds down.

Partnership and shareholder disputes often turn on the founding documents. A partnership agreement or an operating agreement sets out who decides what, how profits split and how someone leaves. When those terms are unclear or ignored, the disagreement moves to court, and the paperwork from the early days becomes the evidence. Contract disputes follow a similar arc, since the wording of the deal and the conduct of the parties carry the weight.

Fraud and unfair competition claims add their own proof burdens. A party has to show what was said, what was withheld and what the difference cost. Handling both the commercial and the litigation ends of these matters means the firm works a case from the deal itself through to the courtroom.

The bankruptcy practice

The firm's bankruptcy work covers Chapter 7, Chapter 11 and Chapter 13 cases. It also handles commercial debt collection, creditors' rights and consumer bankruptcy. Those labels cover both sides of the table: the party seeking relief and the party owed money.

Each chapter follows its own path. Chapter 7 liquidates assets and clears qualifying debts. Chapter 11 keeps a business running while it reorganizes what it owes. Chapter 13 lets an individual with steady income repay over a set period. Creditors file claims and can challenge how a plan treats them. A firm that works all three chapters, plus collection and creditors' rights, sees the process from more than one seat.

Real estate and employment matters

Real estate work at the firm includes residential and commercial actions, partition actions, HOA litigation, boundary disputes and matters tied to mortgage lending and foreclosure. Partition actions ask a court to divide or sell property held by more than one owner. Boundary disputes turn on surveys, deeds and the record of who used which piece of land.

HOA litigation and foreclosure matters carry their own rules and deadlines. A homeowners association operates under recorded governing documents, and disputes over those terms can land in court. Foreclosure and mortgage lending cases run on statutory timelines, so the calendar often shapes the strategy. The firm handling this range keeps property questions under one roof.

The employment practice represents employers and employees. Its cases include discrimination, harassment, wage and hour claims, wrongful termination and WARN Act issues. The WARN Act requires advance notice of large layoffs, so those matters often arrive when a business closes a site or cuts a workforce. Taking both employer and employee cases gives the firm a view of how these claims look from each side of the same statute.

How the team is built

The firm's name comes from two of its attorneys, and its roster lists Katie S. Diemer, Robert C. Diemer, who goes by Bob, and Julia M. Wei. Susan Luce works with the firm as of counsel. The site names these four and gives the firm a small, partner-led shape.

The site does not publish bios, law schools or admission years for the attorneys, so a reader cannot match a name to a particular field from the public pages. As a reviewer, I read the of counsel role as a common arrangement: an experienced lawyer who works with a firm on selected matters without holding a full partner seat. The named roster stays consistent across the pages I reviewed, and the same four attorneys carry the practice areas the firm lists.

Who the firm serves

Diemer & Wei works with clients across San Jose, Silicon Valley and the wider Bay Area. That region packs a dense mix of startups, established companies, property owners and workers, which lines up with the firm's stated areas. Business litigation, bankruptcy, real estate and employment all appear often in a tech-heavy regional economy, and a client near any of those pressures could find a match here.

For someone weighing the firm, the public record gives a clear picture of scope and a short, named roster that has held steady since 2003. The firm handles disputes for both companies and individuals, and it works across state, federal and bankruptcy courts, the same three court systems its own pages have named since it opened.
